The bacon analogue may have a ratio of first to second components of between about 35:65 to about 65:35 and a total fat percentage of about 28% to about 48%. In another configuration, the ratio of first to second components is about 25:75 to about 75:25. In one approach, the bacon analogue is free from alginate binders and free of emulsified meat. In one configuration, the first and the second components are ground to a size of about 0.125-inch to 0.5-inch. After the first and second components are separately mixed and cured, the components are pumped together into a marbled slab having an appearance similar to a pork-belly, which may then be sliced.
