Bread Soup
Put a pint of bread crusts or stale toast into 3 cups of boiling vegetable or fish stock, or in plain water, add 1/4 cup butter, let simmer and as the bread softens mash it with a spoon until it is well mixed with stock. Season according to flavor of stock used. Any left-over gravy or bouillon cubes may be added to stock to enrich it.
A camp soup built from crusts and whatever liquid is at hand. The proportions are loose by design, so the useful notes are about texture, seasoning and what "stock" meant here.
- Measuring bread by volumeA pint of crusts is only a few ounces of dry bread, perhaps 2 to 4 depending how coarsely it is broken. Against 3 cups of liquid that gives a soup you can drink; more bread turns it into a spoonable porridge, which is the older form in much of Europe.
- Butter quantityA quarter cup is 4 tablespoons, generous for three cups of liquid but appropriate for outdoor cooking where fat is the point. Half that amount still gives a smooth, glossy result if you are eating indoors.
- The hinge: mash while it simmersBread soup succeeds or fails on whether the crusts break down completely. Keep the pan at a bare simmer and work the bread against the side with the back of a spoon until no lumps remain; the recipe gives no timing, only the instruction to mash as the bread softens. Rushing it leaves wet lumps of crust suspended in thin broth.
- Choice of breadDense, chewy sourdough or country loaf gives body. Soft sandwich bread dissolves into paste almost immediately and needs less liquid. Toasted crusts contribute a noticeably darker, nuttier flavour than plain stale bread.
- Season at the endThe instruction to "season according to flavor of stock used" matters because bouillon cubes and leftover gravy are already salty. Taste after the bread has broken down, since the starch mutes salt and you will want more than you expect.
- Plain water versionWith water rather than stock, the soup needs help: a crushed garlic clove, a bay leaf, a spoonful of any fat drippings, and pepper. Otherwise it reads as bland rather than plain.
- YieldThree cups of liquid plus bread makes two modest servings as a first course, or one substantial bowl as a meal. Scale by keeping the ratio of one pint crusts to three cups liquid.
Bread soup is one of the oldest ways of eating in Europe, older than the idea of soup as a separate course: broth poured over a slice of bread in a bowl is the original sense of the word sop, which shares a root with soup and sup. Nearly every regional cuisine keeps a version, from Tuscan pappa al pomodoro to Portuguese açorda to the German Brotsuppe. Its appearance in a book on outdoor cooking is a matter of logistics rather than nostalgia: on a camping trip stale bread accumulates, fish stock is a by-product of the day's catch, and a pot of boiling water is already on the fire. The suggestion to enrich the pot with leftover gravy or bouillon cubes points to a twentieth-century kitchen, the cube having been a common shortcut since the early 1900s.
