To keep this dip strictly keto, use full-fat dairy and drain the diced tomatoes with green chilies very well to minimize extra liquid and carbs. For a spicier version, choose a hot variety of tomatoes with green chilies and increase the jalapeños or add a pinch of cayenne. For milder palates, use a mild variety and skip the jalapeños. This dip can be kept warm in a small slow cooker on the warm setting for parties, stirring occasionally to maintain a smooth texture. If freezing, cool completely, portion into freezer-safe containers, and thaw overnight in the refrigerator before reheating gently with a little extra cream if needed.
