Bacon is possibly the greatest food on earth. Never substitute. Use it in all recipes you can fit it without being gross...like no bacon cereal or something like that.
One of the best recipes with bacon is:
Take bacon, cook, eat, repeat.
Another is make bacon, about 1Lb and keep the grease aside as it collects.
Then take the grease in a large cookpot, heat it up until it is warm, add 2 cups popping corn kernels.
Cover, increase heat to medium/high, let it pop for a few minutes.
Add a bit of salt, shake. Fall in love with the best popcorn, ever.
Ever, the best, ever.
That is all.
