Notes
Ingredient Notes
Sweetened Condensed Milk: Be sure to buy sweetened condensed milk, which has sugar added, NOT evaporated milk
Heavy Cream: Use right out of the fridge so it's as cold as possible.
Vanilla: Be sure to use high-quality vanilla, not imitation vanilla.
Raspberry and Lemon Extracts: Look for these near the spices in your grocery store. Be sure to use extracts, not oils, which are more concentrated.
Gel Food Coloring: Use gel instead of liquid food color as it gives a more vibrant color and adds less liquid to the recipe.
Tips
Whip Cream Faster: Make sure your heavy cream is ice cold. Also, chill your bowl and whisk in the freezer for 30-60 minutes.
Fold Gently: Mix your ingredients in gently so your whipped cream doesn't lose it's light and airy texture.
Prevent Ice Crystals: Push a layer of plastic wrap onto the top of your ice cream before putting the lid on.
