Boston Roast

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Mash the beans or put them through a meat grinder.

  2. Add the cheese and enough bread crumbs to form a stiff roll.

Bake and serve

  1. Bake in a moderate oven at 350°F (175°C), basting occasionally with a mixture of butter and water.

  2. Serve with tomato sauce.

  3. Optionally, flavor with chopped onions cooked in drippings.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and sauce barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Kidney beans
Provide the bulk and body of the roll once mashed.
Bread crumbs
Absorb moisture and bind the mixture so it holds its shape as a stiff roll.
Butter
Adds fat and richness to the basting mixture, promoting browning on the surface.

The step that matters

Forming the stiff roll. If the bread crumbs are too few, the mixture stays wet and will not hold its shape in the oven. Adding crumbs gradually until the mixture is firm lets the starch absorb excess moisture and bind the beans or cheese into a sliceable roll.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (kidney beans, bread, butter, tomato, sauce):

  1. Capsicumfits better
  2. Potatofits about as well
  3. Onionthe original
  4. Asparagusfits about as well

Fit is the average pairing score against kidney beans, bread, butter, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
