One spoonful of this sauce and plain fish tacos become the thing everyone requests on repeat.
I used to just squeeze lime over my tacos and call it done. Then I started making this creamy, smoky sauce, and now I genuinely can’t eat a fish taco without it.
It takes 5 minutes, needs zero cooking, and turns out tangy, a little smoky, and rich enough to tie every element of the taco together. Once you make a batch, you’ll be putting it on shrimp tacos, bowls, and nachos too.
Let’s mix it up.
What You’ll Need
- ½ cup mayonnaise
- ¼ cup sour cream
- 1 tbsp adobo sauce from canned chipotle peppers (or 1 tsp chipotle powder)
- 2 tbsp fresh lime juice
- 1 clove garlic, minced
- ½ tsp cumin
- ¼ tsp smoked paprika
- ¼ tsp salt
- 1 tbsp fresh cilantro, chopped
A short list of ingredients that punches way above its weight in flavor.
Tools You’ll Need
- Small mixing bowl
- Whisk
- Citrus juicer
- Small jar or airtight container, for storage
Pro Tips
I’ve made this sauce enough times to know exactly what makes it turn out right.
1. Start with less adobo sauce and add more to taste. The heat and smokiness can vary a lot between cans, so taste as you go rather than dumping it all in at once.
2. Use fresh lime juice, not bottled. Bottled juice tastes flat and won’t give you that bright, tangy edge that makes this sauce so good.
3. Let it sit for at least 10 minutes before serving. This gives the flavors time to meld together into something more cohesive than right after mixing.
4. Mince the garlic finely. Large garlic pieces can overpower a bite unevenly, while finely minced garlic distributes the flavor throughout.
5. Adjust the consistency with a splash of water if needed. If you want a thinner sauce for drizzling instead of a thicker one for dolloping, a small splash of water thins it out easily.

Cooking Time Efficiency Tips
Mince the garlic and juice the lime while you measure out the other ingredients, so everything comes together in one quick step.
Make a double batch since it keeps well in the fridge, so you always have some ready for taco night.
Leftovers and Storage
Store leftover sauce in an airtight container in the fridge for up to 5 days.
Give it a quick stir before each use, since some separation is normal after sitting.
