I make a cream cheese tomato dip for my family but can only eat it on the day I make it. It's just OK if we eat the next day, only if it's been in the refrigerator. I'm looking for a natural preservative that will not change the flavor. Anybody know?
Without knowing the ingredients in the dip it's hard to advise on what to use. If you are using fresh tomatoes in the dip, refrigerating will diminish the tomato flavor. You might try adding a teaspoon of sugar which does boost the natural sweetness and flavor of the tomato. Sugar is also a preservative. Mix the sugar with the tomatoes before adding to the recipe.
