<<Disclaimer: Verify this information before applying it to your situation.>> My son, daughter, and I are all celiac, and are quite sensitive. We use olive oil and balsamic vinegar on our salad every night, and have done so for quite some time. We love it! I also appreciate not having to search for a GF salad dressing. We get the Kirkland Signature Balsamic Vinegar from Costco. The Kirkland Signature on any product is the Costco house brand that signifies it is either "as good or better" than the best on the market. So I'm sure there are no cheap ingredients in this. It think it costs about $9.00 for a liter. Mary California *Support summarization of posts, reply to the SENDER not the Celiac List *
