This is a mayo-based burger sauce built from scratch — homemade mayo as the base, then pickles, red wine vinegar, mustard, and ketchup stirred in. It takes 10 minutes and makes enough for eight burgers. The real reason to make it: you control every ingredient, so it scales cleanly for a cookout without any mystery additives.
What makes this version work
The immersion blender technique is what separates this from a lumpy, broken mayo. You start with the blender sitting at the bottom of the container — all the ingredients underneath the oil — and you hold it there for a full 20 seconds before lifting. That initial blast emulsifies the egg, vinegar, and mustard into a stable base before the oil has a chance to separate. Once the mayo is smooth and thick, the rest is just stirring: finely chopped pickles and a splash of red wine vinegar cut through the richness and keep the sauce from tasting flat on a loaded burger.
Shopping notes
- Oil: The recipe calls for olive, walnut, macadamia nut, or avocado oil. Avoid extra-virgin olive oil — its strong flavor takes over the sauce. A light or pure olive oil, or avocado oil, gives you a neutral result that lets the other flavors come through.
- Ketchup: The recipe specifically calls for ketchup with no high-fructose corn syrup. Most organic or “natural” store brands fit this. Check the label — regular Heinz contains HFCS.
- Pickles: Dill pickles work best here. Bread-and-butter pickles will make the sauce noticeably sweeter, which can clash with the vinegar already in the recipe.
- Vinegar: Red wine vinegar and apple cider vinegar are both listed as options. Apple cider vinegar is slightly milder and a bit fruitier; red wine vinegar is sharper. Either works — just don’t swap in white distilled vinegar, which is too harsh.
If something goes sideways
- Mayo broke and looks greasy or curdled: This usually means the blender was lifted too fast. Start fresh with a new egg yolk in a clean container, blend it briefly, then slowly drizzle the broken batch in while blending. It should re-emulsify.
- Sauce is too thin after combining: The pickles may have added extra liquid. Drain the chopped pickles on a paper towel before mixing them in, especially if you’re making a large batch.
- Sauce tastes flat or one-dimensional: Add a small pinch of salt and a few more drops of vinegar. Taste after each addition — the vinegar is doing most of the brightening work here.
- Sauce is too sharp or tangy: You likely used more vinegar than intended, or your pickles were very acidic. A small spoonful of extra mayo will balance it out without losing the texture.
- Making a double or triple batch and the blender container is too full: Don’t try to scale the mayo in one go — the blender needs room to work. Make the mayo in separate batches, then combine everything in a large bowl when you stir in the dressing ingredients.
Storage and reheating
Because this sauce contains homemade mayo with a raw egg, it needs to stay cold. Store it in a sealed jar or airtight container in the refrigerator and use it within 3 to 4 days — homemade mayo doesn’t have the preservatives that commercial versions do, so don’t push it past that window. Do not freeze this sauce; the emulsion will break when thawed and you’ll end up with a greasy, separated mess. There’s no reheating involved — serve it straight from the fridge. If you’re setting it out at a cookout, keep it in a bowl nested over ice and don’t leave it at room temperature for more than two hours.

Frequently asked questions
Can I use store-bought mayo instead of making it from scratch?
Yes, you can swap in store-bought mayo and the sauce will still work. You’ll lose some of the fresh flavor and the ability to control the oil, but the overall result — pickles, vinegar, mustard, ketchup — will still be a solid burger sauce.
How far ahead can I make this for a cookout?
You can make it up to 24 hours ahead and it will taste better than fresh — the flavors meld as it sits. Just keep it sealed in the fridge until you’re ready to serve, and give it a quick stir before putting it out.
How do I double or triple this recipe without it getting messy?
Make the mayo in separate single batches rather than trying to scale it in one container — the immersion blender needs the right fill level to emulsify properly. Once each batch of mayo is done, combine them all in a large bowl and stir in the dressing ingredients together.
Is it safe to eat mayo made with a raw egg?
The vinegar in the recipe lowers the pH, which helps, but the egg is not cooked. If you’re serving people who are pregnant, elderly, immunocompromised, or young children, use pasteurized eggs to reduce risk.
Can I make this sauce without mustard?
You can leave it out, but the sauce will taste noticeably less complex and the mayo may be slightly less stable since mustard acts as an emulsifier. A small amount — even half a teaspoon — makes a real difference.
What’s the best way to serve this at a backyard cookout without it getting warm?
Nest the serving bowl inside a larger bowl filled with ice. Because this sauce contains homemade mayo with a raw egg, don’t leave it out at room temperature for more than two hours — after that, discard what’s left and pull a fresh portion from the fridge.
