pink variegated lemons... I just might have to slice them and float them in water.
grapefruit ... a sauce. Fresh grapefruit juice some sugar and champagne, maybe some corn syrup if it need some thickness. pour it over a gouda cheese, or over fresh berries, or maybe with some pound cake perhaps. a sorbet sounds good too.
kumquats ... one of my favorite salads. greens, with spinach. toasted slivered almonds, slivered green onions, cubes of cream cheese, and slivered kumquats. mix canola oil, lemon juice or orange juice and some sugar. salt and pepper to taste. I love this wonderful citrus salad.
lemons ... so many options. lemonade, lemon and green beans, lemon mousse, lemon bars, lemon sorbet, lemon creme cookies, lemon chicken, lemon meringue pie - so many options. how about some lemon aioli. crushed garlic, real mayo, lemon juice, salt and pepper. This with fried green tomatoes or with a steamed artichoke to die for!
