Sardine Toast

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Lightly scrape the sardines, honing them if possible.

  2. Lay the sardines on a greased baking tray.

Season and heat

  1. Sprinkle with parsley, seasoning, capers, and vinegar.

  2. Cover with greased paper and heat in the oven at 350°F (175°C) until warmed through.

Serve

  1. Serve on fried bread or toast, garnished with coralline pepper.

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

Sardines
Provide the main fish flavour and tender, flaky texture when gently warmed.
Capers
Add a sharp, briny bite that cuts through the richness of the oily fish.
Vinegar
Adds acidity that brightens the fish and balances its oiliness.
