STONEWALL KITCHEN GLUTEN FREE SEA SALT CRACKERS. These baked, Gluten Free Sea Salt Crackers are delicious! They’re wonderfully light and crisp with a touch of tangy, mineral-rich sea salt but are (surprise!) gluten free. They have a very pleasant, almost buttery biscuit flavor that really stands out and pairs well with fine cheeses, dips and tapenades or crumbled into soups or chili.
