Introduction
Fry sauce is a two-ingredient condiment that takes 30 seconds to make and transforms fries, burgers, and sandwiches with a tangy-creamy finish. The balance of rich mayo and bright ketchup creates a smooth pink sauce that’s stronger in flavor than either ingredient alone. Keep a batch in your fridge during burger season.
Recipe Details
- Prep Time: 2 minutes
- Cook Time: 0 minutes
- Total Time: 2 minutes
- Servings: Makes about 3 tablespoons (enough for 2–3 servings of fries)
Ingredients
- 2 tsp mayonnaise
- 1 tsp tomato ketchup
Instructions
- Combine the mayonnaise and ketchup.
- Mix until the sauce is a strong pink colour.
Variations
Extra tang: Use 1.5 tsp ketchup instead of 1 tsp to push the acidity and reduce richness.
Smoky twist: Stir in a pinch of smoked paprika after mixing to add depth without changing the base ratio.
Garlic kick: Add 1/8 tsp garlic powder once combined to give the sauce a savory punch that pairs well with beef burgers.
Spiced version: Mix in a tiny pinch of cayenne pepper for subtle heat that builds on the back of the palate.
Herb-forward: Fold in a small pinch of finely chopped fresh parsley or chives just before serving for a fresher, less static flavor.
Tips for Success
Mix thoroughly: Make sure you fully incorporate the ketchup into the mayonnaise so the color is even and no streaks remain; uneven mixing leaves you with pockets of pure mayo or pure ketchup.
Taste before serving: Because the ratio is so tight, a slightly heavier hand with ketchup or mayo changes the balance noticeably; adjust the next batch based on what you learn.
Use it immediately or chill: The sauce stays stable in the fridge, but it’s brightest in flavor within the first hour of mixing, so make it close to when you plan to serve.
Double or halve easily: This recipe scales perfectly; multiply both ingredients by the same factor if you’re feeding a crowd, or cut them in half for a single serving.
Storage and Reheating
FAQ
Can I make this ahead?
Yes, you can mix it up to 5 days in advance. Store it in a sealed container in the fridge and stir it briefly before serving if any liquid separates.
What’s the best way to use this sauce?
Serve it as a dip for fries, a spread on burgers or sandwiches, or a topping for hot dogs. It also works as a dipping sauce for fried chicken or onion rings.
Can I adjust the flavor without changing the quantities too much?
Yes; a tiny pinch of salt, pepper, or smoked paprika won’t throw off the balance. Start with less than you think you need and taste as you go.
Does this separate or break over time?
Not significantly if stored properly in an airtight container, though a thin layer of liquid may settle on top. Stir gently before using.
