#51 "2 teaspoons minced onions" instead of "...onion"

[Douglas Squirrel]

Ingredients that use singular and plural forms can be
combined with measurements. When they are,
sometimes we should use the plural:
1 box onions
2 boxes onions
and sometimes the singular:
1 teaspoon onion
2 teaspoons onion
We seem to be using the plural consistently.
