Add your favorite spices to the olives. Oregano, crushed pepper, thyme, rosemary, basil, chilli, garlic, or mustard seed for example. Or add 1 large sliced carrot, 1/2 large onion, and 1/2 large red bell pepper, cutting the onion in 3/8 inch dice and the pepper in thin julienne cuts to create a marinade. Mix the marinade with 2 oz of virgin olive oil and 1 oz of red wine vinegar.
A great winter project or gift for your favorite foodie.
