Five-minute microwave mac and cheese

Stir together half a cup of elbow macaroni and half a cup of water; microwave 4 minutes, stirring halfway.

Stir in about 3 tablespoons of half and half, salt, pepper and a quarter to a third of a cup of white cheddar.

Microwave another minute, until smooth; it thickens a little as it stands.

Optionally finish with the tiniest drizzle of truffle oil and fresh ground pepper.
