I made jello using a packet of unflavored gelatin and white grape juice, because I don’t care for apple juice. I used just 12 ounces, so it felt more like solid food.
Refrigerating half of the prep dulls the unpleasant flavor, as does drinking it through a straw placed at the back of the mouth, to bypass taste buds. But most people shiver if they drink all of it cold, so alternate.
