As a near-fifty year old who has been making sourdough for 6 years, makes homemade mayo with a grated garlic clove and freshly squeezed lemons every couple weeks, and keeps a stash of fine cheeses readily available for all occasions - I'm with the 4 year old. White bread, 2 slices of american, butter - it's hard to beat the sheer comfort, texture, flavor, gooeyness, and simplicity of the classic.
