1. Steam broccoli, covered, 2 minutes. Plunge broccoli into ice water to stop the cooking process; drain and pat dry.
2. Combine mayonnaise and next 3 ingredients (through pepper) in a large bowl. Add broccoli, currants, onion, and bacon; toss well.
Tip: To avoid watery eyes while dicing an onion, peel it first, and chill it in the refrigerator before dicing.
