Over the years 
This is the recipe I used to help earn my Girl Scout Cooking Badge. Nut brittles don’t need to be purchased from a store, you can make them at home, best of all you can choose what nuts you use, be sure to use raw nuts. If you use nuts that are roasted they will burn during the cooking process.
Almond Brittle
1 C. sugar
1/2 C. light corn syrup
1/2 C. water
1/4 tsp. salt
1 Tbsp. butter
1 C. whole unblanched almonds or peanuts
1 tsp. baking soda
Combine sugar, corn syrup, water, salt, and butter in a large pan. Cook stirring constantly, until sugar dissolves. Cover pan one minute to slide sugar crystals from side of pan. Uncover pan insert candy thermometer, cook until mixture reaches soft crack stage. Remove from heat and add nuts. Place back on heat and cook until hard crack stage. Remove from heat and add baking soda. Mix well. Let foam settle just a little before spreading on a well-buttered cookie sheet.
You have the best selection I have seen so far. I do wish though someone had included the sees recipe for 5lb. and using eagle brand milk and the marshmallow in a jar…I use to have this one but lost it when my home burned down. (NOT FROM COOKING!) LOL
