1 1/2 cups orange juice
1 tbsp sugar
3 envelopes unflavored (Knox) gelatin
1 1/2 cups champagne
Strawberries to garnish
Pour juice and sugar into small saucepan. Sprinkle with gelatin and let it bloom for a few minutes. Heat over low heat and stir gently until gelatin is dissolved. Remove from heat and stir in champagne. Pour into 2 oz. plastic cups and refrigerate.
If using strawberries, clean and slice the berries. After the jell-o shots have chilled for ~30 minutes, add the berries. This way they'll be slightly suspended in the mixture.
