I have a Delia recipe for a chocolate dessert using semolina. All I can find on Tesco delivery is Ground rice. Will this suffice? Advice please...

I personally would use it as a substitute, the difference is only between ground durum wheat and ground rice, so for anyone with a wheat intolorance it would be the ideal substitution anyway.

Would ground almonds or hazlenuts give a good result as well?

Ground rice usually reasonable sub for semolina: Ground Nuts would be too oily = can use some as sub for fats inrecipe if trying to reduce saturated animal fats.

Rosti I have nut allergy kiddies to cook for for so no go on the ground nuts anyway....
