Bet you do miss her cooking, those grandmas know. Thats awesome you like Indian Tacos, awesome.
You should really try making fry bread yourself its actually super super simple, although most people I know (of native descent) don't even know how to make it anymore.
Fry Bread (the old school way) taught by my grandmother.
Ingredients:
3/4 bag flour
2 and 1/2 cups luke warm water
1 egg (optional don't need it but it fluffs it up even better)
3 small handfuls of baking powder (old ndn women don't use measuring if it is not liquid)
the three small handfuls should just fit in the palm of your hand
You will also need
Oil
1 large bowl
and a spoon (yep just any spoon)
In your large bowl add your 3/4 bag flour, push some of the flour up the sides of the bowl, so you make a bowl within a bowl and there is still flour on the bottom
If you use 1 egg, mix it in with the 2 and 1/2 cups water
Add water (water egg mixture) into center of bowl (don't mix with flour yet just let it sit in the flour)
Add 3 small handfuls of baking powder and mix into the water, let sit for 5 minutes
With spoon slowly start to add the flour to the water and baking powder mix, with your spoon keep pushing in more flour, stirring it in slowly, (but keep flour on the bottom of bowl)
When your dough gets hard to mix with a spoon, kneed for 5 minutes with hands.
Let rise with cloth over for 25minutes
The trick is* You will still have flour left in the bowl, you don't want to much flour added, you still want the dough slightly sticky, if you grab some it should slightly stick to your hands.
In frying pan, add about 3/4 inch oil heating it just above medium, not smoking.

(yes I've done that)
Now to fry: Take golf ball size pieces from dough (usually best if you take from the edges) , and flatten them out to just under half an inch by stretching on the outsides around the dough
Drop in oil let fry a minute or two on each side til lighly browned. I use just a fork to flip the bread in pan and take it out. After frying I put bread in a strainer with paper towels....easy to just throw in there.
Such simple instructions and ingredients yet it is alot about technique.
This bread is one of my favorite things to eat, frybread goes good with anything.
Someone has to try it. If anyone does. Let me know.
