Have you noticed how expensive flour wraps are in the supermarket? ..they tend to be made from wheat but proper ones are made from cornflour which you can pick up at places like "Janson Hong's" near Peterborough cathederal, & most supermarkets & the ethnic aisle of places such as Asda & Tesco.
If you haven't heard of tortilla's have a look at wikipedia http://en.wikipedia.org/wiki/Corn_tortilla
A pack of proper corn tortilla's could cost nearly £3.00 in the shops, but you can make your own FRESH, much cheaper they are just FLOUR & WATER ..if you eat a lot of these like we do, you could save yourself quite a lot of money by making your own!
If you can't find "Masa Harina" flour then just use some strong wheat flour.
Ingredients ... Flour & water!
This is a really good recipe link
Of course a rolling pin can & will make the flour thin for us to make a handful for a mealtime (though slower) just remember to make all your dough balls the same size & weight for better results. Tortilla's are what we used for my enchilada recipe... you can find that in a previous post
Quick tip 1...we make ours using a large & shallow pyrex bowl lid (it's see through & very strong) so will take a good deal of pressure on it from a grown up.
Quick tip 2... make a set amount of cornmeal flour & try cutting it into 8 (4 knife cuts) with a grown up's help ..that way you know each of the portions is the same size & will take the same time to cook!
