Lemon curd is a sweet, lemony condiment made from sugar, eggs, butter and lemon juice that can be very high in calories and fat. However, if you use the recommended serving size of one tablespoon (as we did in this smoothie recipe), it will not put you over your calorie or fat limit, and it will add a little bit of a creamy satisfying texture. The raspberries provide natural sugars and antioxidants, and the green tea will pep you up in the afternoon due to its naturally occurring caffeine. Oh, and did we mention the myriad of studies proving that green tea prolongs life by preventing disease? Enjoy!
