Planked Shad and Potato Roses

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the fish

  1. Place the shad on a thick wooden board and secure it with tacks.

  2. Season the shad with salt and pepper, then cover it with buttered crumbs.

Shape and bake

  1. Using a pastry bag, shape hot mashed potatoes into rose forms around the fish.

  2. Brush the shaped potatoes with the beaten egg yolk.

  3. Cook in a hot oven at 400°F (200°C) for 25 minutes.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Shad
Main protein; its flesh cooks through in the oven while the crumbs and potatoes finish around it.
Hot mashed potatoes
Form the rose-shaped border and hold their shape while baking, then brown lightly.
Egg yolk
Brushed over the potatoes to promote browning and a glossy golden finish.
Bread crumbs
Buttered crumbs form a crisp, golden crust over the fish.

The step that matters

Shaping the hot mashed potatoes. Potatoes must be hot and piped promptly, because cooling makes the mash stiff and prone to cracking, so the rose shapes lose their definition in the oven.

Swap the potato

How well each one fits the dish's main ingredients (pepper, butter, bread, egg):

  1. Capsicumfits better
  2. Asparagusfits better
  3. Chivefits about as well
  4. Potatothe original

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