Grease a disposable aluminium container with butter and keep aside. Or you can line a tray with an aluminium foil or butter paper and grease it with butter.
To a heavy bottom pan add Caster Sugar (1 cup) and let it caramelize. Once it becomes light brown in color switch off the flame and add Butter (1 tablespoon) and mix well
Now add the chopped Assorted Nuts (1 cup) and combine. I have used cashew nuts and almonds. Pour this to the prepared container and let it cool well.
Once it cools well you can just slide it out of the container. You can just break it to small pieces or grind it to a coarse powder using a rolling pin or a mortar and pestle. You can make butter scotch cake, butter scotch ice cream, etc., using this. Or as a topping for ice cream, cakes, puddings, etc., or just eat it as it is. Store in clean and dry airtight containers in refrigerator.
