1/2 of a pound package of macaroni or medium shells, uncooked. ( I prefer the shells )
1 10-oz package of frozen shrimp, thawed & drained.
1 1/2 cups of chopped celery.
1 small cucumber, sliced.
2/3 cups of mayonnaise.
1/3 cup of sour cream.
3 tablespoons of horseradish sauce, or more if you prefer.
1 tablespoon of grated onion.
Prepare macaroni or shells according to the package.
Then drain. Combine the pasta, shrimp, celery, and cucumber in a large bowl. Blend the mayonnaise, sour cream, horseradish sauce, and onion in a small bowl. Add this mixture to the pasta and toss to coat. Cover and chill thoroughly. Toss again before serving.
