@mightymite Actually, for ice cream? A really good vanilla bean.
now, concretes/frozen custard is a whole other topic ;)
@mightymite Sorry, didn't see the reply - a concrete is a blended frozen custard. Think DQ Blizzard except with frozen vanilla or flavored custard instead of soft serve.
Frozen custard has egg yolk solids in the recipe, and has a richer mouth feel.
Frozen custard has spoiled me to most ice cream lol It's closer to gelato than ice cream, but with more butterfats.
