Sultana or Thompson Seedless is a sort of which fruit?

soildoctor, Raisins are not sultanas, including in Australia

tastes the same to me!

I used to work with grapes and in the USA most raisins are made from the sultana grape, the Thompson Seedless.

And in French. "raisin sec," or dry grape = raisin.

In French, raisin means grape.
