Frozen Yogurt vs Curd vs Greek Yogurt: What Is the Difference?

Every Indian household already understands cultured dairy. We just call it dahi, and we rarely stop to think about how it relates to the yogurt aisle in a supermarket.

Curd (dahi)

Milk set with a spoonful of the previous batch, usually at room temperature overnight. The culture mix in traditional dahi is not standardised — it is whatever is living in that particular household jaman — which is exactly why dahi tastes different from one home to the next.

Texture is soft and set. Acidity varies with how long it stood and how warm the kitchen was. It is the base for raita, kadhi, chaas and lassi.

Yogurt

Commercially, yogurt means milk fermented with two defined cultures, Lactobacillus bulgaricus and Streptococcus thermophilus, under controlled temperature. The point of standardising is consistency — every tub tastes and behaves the same way.

Functionally it is close to dahi. The difference is control, not category.

Greek yogurt

Yogurt that has been strained to remove much of the whey. Removing water concentrates everything left behind, so Greek yogurt carries roughly twice the protein of regular yogurt by weight, along with a thicker body and a sharper tang.

It also carries less lactose, since a good deal of it leaves with the whey. That is why some people who struggle with milk manage Greek yogurt comfortably.

Frozen yogurt

Yogurt base — cultured exactly as above — then sweetened, flavoured, aerated and frozen. It is a dessert built on a cultured foundation, not a health food and not a substitute for the others.

Compared with the spoonable versions, frozen yogurt has sugar added and air whipped in. Compared with other desserts, it brings protein, calcium and live cultures that they simply do not have.

A quick comparison

The point they share

All four are alive. Every one of them delivers bacteria that arrive in your gut in working order — and that, rather than any single nutrient, is the reason cultured dairy has held a place in Indian kitchens for as long as anyone can trace.

Frozen yogurt simply moves that idea into the dessert course.
