Boone counts every distinct named ingredient on Burger King’s published component lists, including sub-ingredients, and removes duplicates, so salt appearing in four components counts once. Additive class names are dropped and the named substance kept, so “leavening (baking soda)” counts baking soda once. Ice and water added at the counter are not counted. Raw covers whole foods and basic kitchen staples such as flour, sugar, salt and oil. Manufactured covers substances that only exist as an output of industrial processing. Every figure here is a minimum. The build uses a BBQ sauce.
