I have made this before and it is what the many restaurants use. Especially the ones that use a lot of cheese for Mexican dishes. They make it by the tub full. I use a loaf pan, oiled. Easier to store in that shape. I have never thought any food product couldn't be made at home as long as I had the right ingredients. Great restaurants make everything from scratch, cost the fraction of buying pre made. Better the food the more customers the more staff to do the prep work in the kitchen.
