Look for radishes that are fairly uniform in size, so they will fit nicely into your ice-cube tray.
- 14 medium radishes
- 7 pimiento-stuffed olives, halved crosswise
- 16 ounces gin or vodka
- 1 ounce vermouth
Trim stem and root ends of radish. Use a paring knife to scrape red skin from radish, leaving just enough to give a veiny appearance. With a small melon baller, cut a hole in radish, about 1/2 inch in diameter. Fit an olive half, cut-side facing out, into hole. Place radish in ice-cube tray. Repeat with remaining radishes. Fill tray with water; freeze.
Mix vodka or gin with vermouth; stir with ice. Divide eyeball ice cubes among four glasses. Strain martini; pour into glasses, and serve.
