Frequently asked questions

How long does Frozen Watermelon and Jalapeño Margarita Slush take to make?

Total time is about 5 minutes (5 min prep + 0 min cook). Most home bartenders find this fits a single afternoon; scale up the batch for parties or pitchers.

How do I store leftover Frozen Watermelon and Jalapeño Margarita Slush?

Refrigerate any leftover frozen watermelon and jalapeño margarita slush in a sealed pitcher or jar for up to 3–4 days. Do not reheat — drinks are served chilled. If the recipe uses sparkling water or fresh herbs, hold those back and add fresh just before pouring so the drink stays bright and fizzy.

Can I substitute ingredients in Frozen Watermelon and Jalapeño Margarita Slush?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Frozen Watermelon and Jalapeño Margarita Slush for a different number of people?

The recipe is written for 1 servings. Multiply each ingredient by (your serving target / 1). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
