Is there a common kitchen thing that might be a suitable sub for agar? I REALLY want to make the No-Bake Black Bottom-Peanut Butter Silk Pie from VwaV after seeing someone's drool-worthy picture of it over in veganfoodpics. But I couldn't find any agar at Whole Foods tonight! Do I have to wait until tomorrow when I can go check out another natural food store, or is there any hope for an easy replacement tonight?
Alternatively, is anyone familiar enough with that recipe to know whether you can just leave it out? It's 3 tablespoons, which seems like enough that it's probably important...Help!
