Whether it's lemonade or your favorite cocktails, many beverages rely on a sweetener like simple syrup. This can become a challenge when you're reducing or eliminating sugar to follow a keto diet. However, there's no need to skip the homemade drinks because it's easy to make a sugar-free simple syrup.

Several sweeteners are designed to replace sugar, but not every one of those works well in simple syrup. Some, such as stevia, have a bitter taste that can throw off a drink's balance of flavors. Erythritol and xylitol sweeteners (including those with monk fruit) do not dissolve well; they seem to work in a hot syrup but will crystalize once cooled. The solution to both of these issues is to use an allulose monk fruit sweetener.

Produced by a few companies, the allulose sweetener dissolves very well in hot and cold water. More importantly, the taste of monk fruit mimics the sweetness of regular sugar without a bitter aftertaste. When making a syrup, you simply have to use this sweetener as an equal-measure substitute for sugar in a standard simple syrup recipe.

There are many exciting possibilities for this zero-calorie simple syrup. For instance, you can add flavor and, in some cases, even use it to replace the sugary liqueurs often used in cocktails. It keeps well, so you can make a large batch and have it on hand whenever you want to make a sugar-free drink.

  • 1 cup water

  • 1 cup granulated allulose monk fruit sweetener

How to Use Keto Simple Syrup

Generally, this simple syrup can replace sugar syrup measure-for-measure in any drink recipe. As with any syrup, you might want to add a little more or less to drinks to adjust the sweetness to your taste. Use it as the base for homemade sodas, the sweetener for lemonade, or in any drink that calls for simple syrup, agave nectar, honey, or other liquid sweeteners.

Recipe Variations

  • Infuse the syrup with herbs, spices, or other botanicals. Add the flavoring ingredients while the syrup simmers and strain it out once cool (or before if it reaches your desired flavor). Cinnamon, lavender, mint, and vanilla are excellent options.
  • For a quick flavor boost, add about 1/4 teaspoon of a flavoring extract to the cooled syrup, and adjust to taste.
  • Use this syrup as a base for a homemade sour mix by adding lemon and/or lime juices.
  • Create a sugar-free triple sec substitute by adding a tablespoon of orange juice and orange peels before simmering. Use this for margaritas, cosmopolitans, and any other cocktail that calls for orange liqueur.
  • Similarly, play with fruits, such as cherry, pomegranate, and raspberry, to replace flavored liqueurs and syrups. Use fresh fruits or fruit juice, but keep in mind that fruits have their own sugars; you just won't be adding any with the syrup base.
