1 sun-dried tomato packed in oil, drained and minced
1 garlic clove, minced
1 1/2 teaspoons freshly grated or prepared horseradish
1 teaspoon fresh lime juice
1/4 teaspoon freshly ground pepper
1/4 teaspoon coarse salt
Combine all of the ingredients in a mini-processor and pulse until smooth. Scrape the butter onto a 12-inch square of plastic wrap and roll it into a 2-inch cylinder; twist the ends tightly to seal. Refrigerate the flavored butter just until firm, about 30 minutes.
The butter can be refrigerated for up to 3 days. Let soften briefly before using.
