Ingredients
2 servings

Everyday kitchen measurements
For 2 servings. Use a small 180 ml paper cup, a level eating spoon (about 15 ml) and a small teaspoon (about 5 ml).
How to fill the cup and spoons
Use the same cup and spoons throughout. Their sizes vary, so these amounts are approximate. Spoon flour in loosely and level the top without pressing. Measure vegetables after chopping, without packing them down. The amounts in g/ml are the original reference quantities. For part of a pack, use the specified pack weight and divide the contents evenly.

Essential
Use ripe, chilled watermelon; it provides the fruit base. Keep cut fruit cold until serving.

Substitute available
If Plain soju — 1/2 paper cup (90 ml) is unavailable
If soju is unavailable, use the same amount of unflavored vodka; it will no longer be a soju cocktail and may be stronger, so check the label.
-
Substitute available
If Plain sparkling water — 1 paper cup (180 ml) is unavailable
Use unsweetened soda water in the same amount. Lemon-lime soda works but makes the drink sweeter.
-
Optional
Omit if the watermelon is already pleasantly tart, or use lemon juice in the same amount.
-
Optional
Chill the glasses and ingredients instead if ice is unavailable.
Tap each ingredient as you prepare it. Check product labels for egg, soy, sesame, wheat, fish or shellfish where relevant.
Step-by-step cooking
-
Step 1

Cut 2 paper cups of chilled seedless watermelon into small cubes. Crush it with a fork in a bowl until juicy but still a little textured; divide the crushed fruit between two clean glasses.
-
Step 2

Pour 1/4 paper cup (45 ml) plain soju into each glass. Add 1/2 tablespoon lime juice to each if using. Stir gently so the fruit and soju combine.
-
Step 3

Add ice if using. Slowly top each glass with 1/2 paper cup (90 ml) plain sparkling water. Stir once and serve at once; do not store a mixed drink for later.
Finished dish

Use plain soju, not a sweet flavored bottle, so the watermelon remains the main flavor. This is a smaller, sparkling variation of subak soju. For adults of legal drinking age only. Alcohol strength varies by bottle; taste before adding extra syrup. Serve one glass at a time and do not drive after drinking. Keep perishable ingredients refrigerated.
