Place cheese cubes in a resealable plastic bag or in a jar. In a screw-top jar combine oil, lemon peel and lemon juice, garlic, peppercorns, and crushed seeds. Cover and shake well. Pour mixture over cheese. Seal bag or cover jar. Turn to coat. Refrigerate, covered, up to 3 days, turning occasionally.
Let cheese stand at room temperature for 1 hour before serving. Transfer cheese with marinade to a serving bowl. Makes 12 to 16 servings.
