Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

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 mashed potatoes and shape them into small platters around the base of the dish.
Score the potatoes with a knife and brown them under the broiler or in a 400°F (200°C) oven.
Arrange each vegetable separately in the spaces between the potato platters.
Garnish the outer edge with curled parsley, arranging it neatly to maintain heat.

Recipe from a historical cookbook (Internet Archive).

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.
