Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Asparagus
Forms the main vegetable, with tender heads and firm stalks that hold their shape when boiled.
Sea kale
Provides the main vegetable, with a tender texture and a mild, slightly salty flavour.
Fresh butter
Adds richness and a smooth, savoury coating to the hot vegetables.

The step that matters

Drain the vegetables carefully after cooking. Asparagus and sea kale are delicate, and overcooking or rough handling makes them soft and broken. Draining promptly and gently keeps the stalks intact and stops excess water from diluting the sauce or butter.

Swap the asparagus

How well each one fits the dish's main ingredients (sugar, vinegar, pepper, butter, tarragon):
