FAQ

Can I make this vegan?
Swap heavy cream for full-fat coconut cream and use a plant-based sweetener like allulose.
Can I use fresh mint leaves?
You can steep fresh mint in warm cream, then chill and blend. Peppermint extract is faster and more authentic.
Can I make this ahead of time?
Serve immediately for best texture. Keto version can be chilled up to 24 hours, but may need a quick blend before serving.
Can I increase sweetness?
Yes, taste before blending fully and adjust allulose as desired.
