Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Irish Potatoes for Dinner or Luncheon
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Peel and slice the potatoes into thin slices.
Soak the slices in cold water for about 1 hour, changing the water 2-3 times.
Boil the potatoes quickly until tender, then drain the water.
Make the mash
Cream the potatoes in the same vessel using a silver fork.
Add butter and salt, then mix in the milk until light and creamy.
Fold in chopped parsley and celery.
Bake and serve
Transfer to a baking dish, top with grated cheese and cracker crumbs, and dot with butter.
Bake in a hot oven at 400°F (200°C) until browned.
Garnish with parsley before serving hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the casserole, giving a soft, starchy body once creamed.
- Milk
- Adds moisture and richness, loosening the mash into a creamy texture.
- Butter
- Adds fat for richness and flavour, and helps the top brown in the oven.
- Cheese
- Melts into the top layer and browns during baking, adding savoury flavour.
- Cracker crumbs
- Form a crisp, browned topping that contrasts with the creamy potato beneath.
The step that matters
Boil the potatoes quickly until tender. Potatoes that are overcooked or waterlogged turn gluey when creamed and hold too much water, so the mash becomes loose. Drain thoroughly and cook only until tender.
Swap the celery
How well each one fits the dish's main ingredients (potato, butter, milk, parsley, cheese):
- Thymefits better
- Dillfits about as well
- Nutmegfits about as well
- Celerythe original
Fit is the average pairing score against potato, butter, milk, parsley, cheese. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
