Do you have proportions you wouldn't mind sharing?
I want to try making it for my co-workers. Do you have to serve them hot, or can you let them cool overnight?

Here's the actual recipe given to me by one of the women:
Ingredients:
1 20 oz. bag small round Tostitos
½ cup butter
½ cup corn syrup
½ cup granulated sugar
2 Tablespoons soy sauce
2-3 Tablespoons black sesame seeds
Cooking Instructions:
Melt butter on low heat and then add sugar, syrup, soy sauce, and sesame seeds and mix until the sugar is dissolved.
Place ½ the Tostitos in large bowl, add ½ the syrup mixture and slowly mix thoroughly, trying not to break chips. Put into a large greased pan. Repeat with the remaining Tostitos and mix well.
Bake in 250 degree oven for 1 hour. Mix every 15 minutes (do this or your snacks will stick into one big clump.)
Turn out the chips onto a large surface and try to separate as many as you can during that short period between burning your fingers and the time the chips are too cool to separate. As soon as they no longer stick to each other, store them in an air-tight container...if they last long enough for storing them at all.
Add shredded nori (seaweed) or rice seasoning for different flavors.
