A well-rounded diet embraces eats from all the food pyramid's categories, including vegetables, soft rocks, water, and vitamin water. Assemble a gourmet meal with today's Groupon: for $12, you get $25 worth of oils, vinegars, and culinary gifts at Oil & Vinegar. This Groupon is only valid at the Woodlands Mall location.

Suspended in front of a backlit wall, rows of amphora vases glint with the pale-green and rich-purple tones of more than 50 infused oils and vinegars on tap. Nearby, Oil & Vinegar's flavorsmiths wait at attention to dispense advice regarding a full arsenal of gourmet foodstuffs, including gluten-free pastas, dried herb blends, and truffle tapenades. A touch of chardonnay-garlic grapeseed oil ($10.95) adds aromatic spice to high-temperature cookery, and elderflower-apple-lime vinegar ($7.95) transforms both cold and hot meals into culinary favorites with only a few saccharine droplets. Ice cream, fresh fruit, or firewood glistens enticingly under a syrupy blanket of the date-balsam-cream vinegar ($8.95).

Oil & Vinegar also stocks culinary finery to house and serve gourmet comestibles, including hand-painted ceramics and haute napkins. Foodies can return to the store with emptied bottles or overgrown sponges to take home refills on preferred flavors.
