Ice Cream

Fordi's Fantastic Ice cream

This scalable, generic ice cream recipe provides a smooth, creamy ice cream. The carrageenan provides good stability against short bursts of heat (so you can bring it to a party) and limits crystal formation during cooling. The starch improves the overall mouth-feel of the custard and helps with stability.

This recipe can be used for sweet or savory ice creams; the sugar is limited to 6.25g/serving - only about 25 kcal - so is only used to aid in maintaining the emulsion, and doesn't provide much of the sweetness. Add up to 50g of sugars or syrups with the mixins to make a sweeter dessert, but avoid overwetting the custard.

Up to half of the milk may be substituted for alcoholic ingredients.

For the scalable form of the recipe:

  • Percentages are by mass
  • Optional ingredients' percentages are marked in parenthesis (50%), and do not count towards the total mass
