I love this recipe to create realistic looking water. Tint to your liking.
PIPING GEL
Yields 1/2-cup
INGREDIENTS:
• 1/4-cup cold water
• 1/4-cup corn starch
• 1/2-cup light corn syrup
• 1 tsp clear flavor extract (optional)
• Gel food coloring (optional)
STEP 1:
Combine the cold water and corn starch in a heat-proof container. Whisk until no cornstarch lumps remain. Whisk in the corn syrup until combined.
STEP 2:
Microwave for 2-3 minutes on high, stopping every minute or so to stir. The mixture will bubble up and boil before thickening to the consistency of hair gel. Allow the mixture to cool to room temperature before adding flavoring or color.
STEP 3:
If the piping gel becomes too thick, add a tiny amount of water until you achieve your desired consistency. Store piping gel refrigerated in an airtight container for up to three months.
