Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Oatmeal Cookies No. 1
Ingredients
Directions
The book says “a medium oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream together the butter and lard.
Add the granulated sugar and mix well.
Sift together the flour, baking soda, and cinnamon three times.
Add the sifted mixture to the butter mixture.
Stir in the rolled oats and seeded raisins until thoroughly mixed.
Beat the eggs lightly, then add the evaporated milk and water.
Combine the egg mixture with the cookie dough.
Bake
Drop spoonfuls of the dough onto a greased baking sheet.
Bake in a hot oven at 400°F (200°C) until golden.

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.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Butter
- Adds fat and richness, helping the cookies stay tender and spread.
- Lard
- Adds fat that keeps the cookies tender and crumbly.
- All-purpose flour
- Provides the structure that holds the cookies together as they bake.
- Eggs
- Bind the dough and add structure and moisture to the cookies.
- Baking soda
- Reacts with the dough to help the cookies rise and brown.
- Granulated sugar
- Sweetens the dough and helps the cookies brown as they bake.
The step that matters
Sifting and combining the dry ingredients evenly. Sifting the flour, baking soda, and cinnamon three times distributes the leavener evenly so the cookies rise uniformly. Uneven mixing can leave pockets of baking soda that cause bitter spots or uneven rising.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, flour, cinnamon, oats, egg, evaporated milk):
- Vanillafits better
- Raisinthe original
- Pumpkinfits about as well
- Coconutfits about as well
Fit is the average pairing score against butter, sugar, flour, cinnamon, oats, egg, evaporated milk. Candidates are from the same food group and used in at least 100 recipes.
