Ingredients for at home yum yum sauce
Nine ingredients, ten minutes, and a sauce that rivals restaurant quality.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | ¾ cup | High-quality, not watered-down |
| Mayonnaise 🥫 | ½ cup | Full-fat for creamy texture |
| Rice Vinegar 🍶 | ¼ cup | Seasoned preferred for depth |
| Worcestershire Sauce 🧂 | 1 tbsp | Ensures umami complexity |
| Granulated Sugar 🍚 | 2 tbsp | Fine grain preferred |
| Garlic Cloves 🧄 | 2 cloves | Minced for subtle flavor |
| Fresh Ginger 🌿 | 1 tbsp | Grated, for zesty kick |
| Red Chili Flakes 🌶️ | 1 tsp | Adjust for heat preference |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Sesame Oil 🫒 | ½ tsp | Toasted, for aromatic finish |
The ketchup and mayo form the sauce's foundation, so quality matters. Heinz or Hunt's ketchup delivers consistent flavor, while Hellmann's or Duke's mayo provides the perfect creamy base. For vinegar, Kikkoman seasoned rice vinegar adds subtle sweetness and depth—don't substitute with white vinegar. The garlic and ginger should be fresh; pre-minced jars lose potency quickly. If you're short on time, Trader Joe's carries pre-grated ginger in convenient packages. Sesame oil is the secret to that authentic aroma; Kadoya or La Choy are reliable brands. The red chili flakes should be vibrant, not dull—check the expiration date as they lose heat over time.
No rice vinegar? Apple cider vinegar with 1 tsp sugar works in a pinch, though the flavor will differ slightly. Substituting mayo with Greek yogurt creates a tangier sauce, but the texture will be thinner. For extra heat, add 1/4 tsp sriracha alongside the chili flakes. The Worcestershire sauce is non-negotiable for that umami depth—Lea & Perrins is the gold standard, but Annie's is a budget-friendly alternative. If you're making this ahead, reduce the sesame oil to 1/2 tsp and add it fresh before serving to preserve its aroma. The sugar can be swapped for maple syrup at a 1:1 ratio for a more complex sweetness.
This sauce reaches peak flavor after 30 minutes of chilling, so plan accordingly. Store in an airtight container in the fridge for up to 2 weeks, though the texture may separate slightly over time—just stir before using. For a restaurant-style presentation, strain through a fine-mesh sieve to remove any bits. The sauce reheats beautifully; gently warm in a saucepan over low heat, stirring constantly, until just hot. For meal prep, divide into small containers—ice cube trays work perfectly for single-serving portions. Freeze for up to 3 months if needed, though texture may change upon thawing.

Step-by-step instructions for yum yum sauce
This sauce comes together in minutes with precise technique and balanced flavors.
Combine Wet Ingredients for Smooth Base
In a medium bowl, whisk together the 0.75 cup ketchup, 0.5 cup mayonnaise, and 0.25 cup rice vinegar until fully incorporated. The mayonnaise should blend seamlessly with the ketchup and vinegar, creating a thick, cohesive base. I like to use a fork for this step—it gives me better control over the mixing process without introducing too much air.
Next, add the 1 tablespoon Worcestershire sauce and 2 tablespoons granulated sugar. Stir well until the sugar dissolves completely. The sugar will help balance the acidity from the rice vinegar while enhancing the sweet-chili profile. At this stage, the mixture should still be smooth but slightly thicker than the individual ingredients. If you notice any graininess from the sugar, whisk more vigorously for 10-15 seconds until fully dissolved.
Add Aromatics and Build Complexity
In a separate small bowl, finely mince the 2 cloves garlic and grate the 1 tablespoon fresh ginger using a microplane or fine grater. The goal is to create a paste-like consistency for both ingredients—this ensures even distribution throughout the sauce. Add these to the wet mixture along with the 1 teaspoon red chili flakes and 0.5 teaspoon salt.
Stir thoroughly to combine, making sure the chili flakes disperse evenly. The sauce should now have a slightly thicker texture with visible specks of garlic, ginger, and chili. Here's the thing—don't worry if it looks a bit uneven at this stage. The final texture will smooth out as we incorporate the sesame oil in the next step. Taste the mixture now—you should detect the bright acidity of the vinegar, the sweetness from the sugar, and the underlying heat from the chili flakes.
Finish with Sesame Oil and Rest
Drizzle in the 0.5 teaspoon toasted sesame oil while stirring continuously. The sesame oil adds a nutty aroma and subtle depth that ties all the flavors together. Stir for an additional 30 seconds to fully incorporate, then taste again. At this point, you may want to adjust the balance—add a pinch more salt if needed, or a touch more sugar if the acidity feels too sharp.
Transfer the sauce to an airtight container and let it rest at room temperature for 10 minutes before serving. This resting period allows the flavors to meld completely, resulting in a more cohesive taste profile. The sauce will thicken slightly during this time, which is perfect for dipping or drizzling. For best results, use within 24 hours, though it can be refrigerated for up to 5 days—just give it a quick stir before using to restore the ideal consistency.
Pro Tips For Making At Home Yum Yum Sauce
- WHISK IN STAGES: Mix the mayo and ketchup first—this keeps the sauce from breaking when you add the vinegar later. After that, stir in the Worcestershire and sugar slowly, or you’ll end up with a gloppy mess that’s impossible to fix.
- CHILL BEFORE USING: Let the sauce sit in the fridge for at least 30 minutes after mixing. The flavors meld better when cool, and the texture thickens up nicely—no more runny drips ruining your fries or nuggets.
- MEASURE THE VINEGAR: Use 1 tablespoon of rice vinegar, not the splash-and-pray method. Too much and your sauce tastes harsh; too little and it lacks that bright tang that makes the whole dish pop.
- SWEETEN THE SUGAR GRADUALLY: Add the granulated sugar 1 teaspoon at a time while tasting. The recipe might call for 1 tablespoon, but store-bought ketchup is already sweet—you might not need it all, and skipping this step can make the sauce cloyingly sugary.
Storing and reheating this dish
Refrigerator Storage
Store your homemade yum yum sauce in an airtight container (I love Pyrex glass jars for this) in the fridge—it keeps beautifully for up to 2 weeks. The sauce may separate slightly over time, but a quick stir with a silicone spatula restores its silky texture.
For best flavor, use within 5 days of making it. 🌡️
Pro tip: Divide the sauce into smaller portions (like ice cube trays) before freezing if you want single-serving convenience. This prevents freezer burn and makes it easy to thaw just what you need.
Freezing for Later
For longer storage, freeze the sauce in airtight containers or ziplock bags with all air removed. It maintains quality for up to 3 months, though the texture may become slightly grainy upon thawing. To restore smoothness, gently reheat in a saucepan over low heat while stirring constantly. 🧊
Reheating Like a Pro
To warm the sauce, transfer it to a small saucepan and heat over low-medium heat for 2-3 minutes, stirring constantly. Avoid high heat—it can break down the mayo and make the sauce separate.
For a quick fix, microwave in 20-second bursts until just warmed through. Always taste and adjust seasoning after reheating. ⏱️
Texture Fixes
If your sauce looks too thick after refrigeration, thin it with 1 teaspoon of warm water or rice vinegar while stirring. For a thicker consistency, chill it uncovered in the fridge for 30 minutes to let excess moisture evaporate.
The key is balance—your sauce should coat the back of a spoon but still flow freely. 💡
Meal Prep Hack
Make a double batch and store half in the fridge for immediate use and half frozen for later. This way, you always have fresh sauce on hand for last-minute cravings. Just remember: freshly made sauce always tastes best, so prioritize using the refrigerated portion first. ✨

Frequently asked questions
Can I make this yum yum sauce without mayo?
Yes! For a lighter version, replace the mayo with ½ cup Greek yogurt—it adds tanginess but keeps the sauce thinner. For a richer texture, try ¼ cup mayo + ¼ cup sour cream. The sauce will have a slightly different mouthfeel but still deliver that signature sweet-tangy balance.
How spicy should the sauce be?
The 1 teaspoon red chili flakes provides mild heat—adjust to taste! For extra kick, add ½ teaspoon cayenne pepper or 1 teaspoon sriracha. For a smoky depth, swap ½ teaspoon smoked paprika for half the chili flakes. Always taste before serving.
Why does my sauce look separated after refrigerating?
This is normal! The mayo and vinegar naturally separate when chilled. Simply stir vigorously with a whisk or immersion blender until smooth. For prevention, store in a glass jar and let it sit at room temperature for 5 minutes before refrigerating. The texture will stabilize better.
What's the best way to use leftover sauce?
Beyond dipping, try it as a glaze for grilled chicken or baked tofu. Drizzle over spring rolls or fried rice for instant flavor. For a fusion twist, mix 1 tablespoon into mayo for sandwiches or burgers. The sauce reheats beautifully—just warm gently over low heat while stirring.
Can I make this sauce ahead for a party?
Make it 1 day ahead for deeper flavor. Store in an airtight container in the fridge. For serving, transfer to a slow cooker on warm setting for 20 minutes** to keep it creamy. Label containers clearly—this sauce disappears fast at gatherings!
