Why it works: Blue cheese and pear share more aroma than cooks usually use. They rank in the top 3% of all ingredient pairs, and 40 recipes mention both. Both carry ethyl pentanoate, which smells yeast, fruit. The science ↓
The recipe
6 servingsIngredients
Contains: milk, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Whisk the ketchup, distilled white vinegar, white sugar and salt together in a large bowl until the sugar dissolves.
Slowly drizzle in the canola oil while whisking constantly until the dressing is smooth and emulsified.
Toast the chopped walnuts in a dry skillet over medium heat for 3 to 4 minutes, stirring often, until fragrant, then let them cool.
Peel, core and chop the pears. Chop the romaine and the red onion.
In a large salad bowl, combine the chopped romaine, pears, red onion, toasted walnuts and crumbled blue cheese.
Pour about two-thirds of the dressing over the salad and toss gently to coat. Add more dressing to taste and serve right away.

Fit is the average pairing score against ketchup, vinegar, sugar, canola oil, blue cheese, pear, walnut. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
