If you haven’t started thinking about it yet, it’s time. Mother’s Day is coming up at the end of this week. Of course you could go out and buy a card, but if you’re mom is online-saavy, you can save gas, tax and time — and donate to a great cause by opting to send an e-card via www.ToastToMom.com. The site is a joint fund-raising (and publicity) venture between Clos du Bois and The National Coalition for Women with Heart Disease. Clos du Bois will donate $1 to the organization for every e-card sent. The site includes some great recipes from the book, and an offer to buy a Mom’s Day gift basket for $75 that includes a pair of wines and a copy of “WomenHeart’s All Heart Family Cookbook,” ($29.95, Rodale.) The book has lots of flavorful recipes that use the kind of foods we should be eating: whole wheat pasta, sweet potatoes and arugula, and broccoli-barley pilaf. You didn’t ask, but I’ll just tell you that Clos du Bois wines are always solid, and their dry rose is a good pick because it’s ultra food-friendly. If you can resist buying something while you’re on the site, sending a giant batch of e-cards will cost you nothing besides a little time.
