Bloody Mary Tomatoes KETO TIP: When looking for hot sauces that are keto, check the ingredients. Don’t just look at the carbohydrate count. Most serving sizes are so low that they may only have a carb or two and it doesn’t look bad. But most have sugar. I used Franks hot sauce which is made of: aged cayenne red peppers, distilled vinegar, water, salt, and garlic powder. You can get this at most grocery stores as well as Costco.
