Honey Lime Dressing

In a blender or food processor, mix sugar, honey, mustard, lime, and pineapple juice. Blend briefly, slowly adding oil. Continue to mix until all oil is added and well-incorporated. Pour into a quart container with tight-fitting lid. Store in refrigerator. This dressing keeps well for several weeks. This dressing makes a delicious salad when used on radicchio greens. Add grated lime zest sprinkled on top of your salad for a refreshing taste.
