I made cinnamon spice pecans and almonds for Christmas presents. They are more for just munching. I have made the other kind like for the salads.
In a saute pan, put some butter, brown sugar and cinnamon, melt it all together. Add a bit of white Karo syrup or if you don't have any, a wee bit of regular pancake syrup. Make sure it doesn't burn but you want to make sure that the sugar is all melted and not grainy. VERY, VERY carefully taste a smidgeon on a spoon...to make sure your proportions make it taste ok.
Toss in the pecan halves and make sure they are all covered. Lay out on wax paper until they are cooled. Or you can serve them warm on salad.
These are also really good broken up and put on top of whipped sweet potatoes (with butter, cinnamon, little bit of honey, bit of orange juice) in a casserole dish and then baked.
