Home kitchens constantly need new spices, since old spices often spoil, lose their potency, or mischievously turn into bottles of cologne. Keep your cooking edible with today's Groupon: for $15, you get $30 worth of spice blends, olive oils, vinegars, and more at both Galena Garlic Company locations in Galena and Geneva.

Blending exotic spices, artisan sea salts, and organic garlic, Galena Garlic Company equips stockpots and spice racks with a wealth of flavorful seasoning selections. Grown in Galena, various varieties of whole garlic ($12/pound, available starting mid-July), including german white and music, are ideal for sautéing or broiling. Seasoning savants blend aromatic spices in small batches to help cooks create dishes free of frantic, last-minute spice-trade journeys to India or Texas with seasonings such as BB Que rub ($7). An arsenal of more than 14 fresh olive oils, such as the antioxidant-rich Arbequina extra-virgin olive oil ($17), pair exquisitely with a variety of flavored balsamic and wine ($17) vinegars to create consummate bread dips, salad dressings, and treats for neighborhood tin men.
