Time25 hours

Ingredients

1 envelope (¼ ounce ) unflavored gelatin
¼ cup cold water
2 large carrots , grated very fine

Refrigerate for 25 hours.
If the mixture becomes too jelled to spread well, add ⅓ to ½ cup more mayonnaise.

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

What each ingredient does

Unflavored gelatin: Sets the vegetable mixture so it holds together and spreads without running out of the sandwich.
Mayonnaise: Adds fat and moisture, binding the vegetables and keeping the filling soft and creamy.
Carrots: Add moisture, subtle sweetness and color; grating them fine helps them blend into the spread.
Celery: Adds crisp texture and a fresh, mildly savory flavor to the filling.
Cucumbers: Contribute moisture and a cool, fresh crunch to the filling.
White bread: Provides the structure that holds the filling, with trimmed crusts giving soft, even slices.

The step that matters

Refrigerate the gelled mixture before spreading. Gelatin sets as it chills, so the mixture needs time to firm up. If it is spread too early it will be runny and soak the bread, and if it is left too long it becomes stiff, which is why the record allows extra mayonnaise to loosen it.
