I had this brainwave sometime last year when sweet potato was in season. I think I was looking at desserts made with sweet potato, but as usual, I lost interest, probably because there were too many ingredients I would have to buy just for this, and left it to languish in the vegetable basket. Then when my conscience nudged me, I baked it or pressure cooked it - I really don't remember now - and sprinkled it with cinnamon. And the strangest thing happened - the smell of my grandmother's French Toast arose in my kitchen. She used to make it for breakfast often when I was a child, with bakery bread that came in thicker slices than today. I've never been able to replicate the taste. I even took it to work and shared it with a couple of colleagues who liked it.
My method
This time, I simply steamed the sweet potato in a colander over a pan of water that was boiling something else.
I peeled and sliced it, put it on an oiled tava/skillet, and let it cook on both sides, adding a few drops of extra oil whenever I felt the slices would begin to burn.
Once they are crisp and brown around the edges, sprinkle a tiny bit of salt and some powdered cinnamon, let sizzle, pause for a few seconds. Turn them over. Repeat.
I've even got step-by-step photos for you below (from bottom upwards)!
I'm not recommending any amount - I went with pinches of cinnamon till I arrived at the taste I liked. A few slices make a great mid-workday snack.
Bon appetit!
