Ghee is made from butter and is sometimes called clarified butter. Although it is technically a dairy product, just like milk, yogurt, ice cream, cream, butter and cheese, it is made only from the fattiest part of dairy and contains very little milk protein.
The main proteins found in milk are called casein and whey, which are found in all dairy products. However, the higher the fat content of a dairy product, the lower its protein content. For example, 1 cup of whole milk has close to 8 g of protein, while 1 tbsp. of butter has 0.1 g of protein and ghee has no detectable amount of protein. However, ghee may still contain traces of the milk protein casein.
If you have a milk or casein allergy or an intolerance to milk protein, it is best to avoid even trace amounts of milk protein. To prevent any potential health problems or side effects of milk protein, you should completely avoid all dairy products, foods derived from dairy products and processed foods containing ingredients derived from dairy products. Because ghee is made from a dairy products, you should not consume it if you are allergic to ghee, unless you find a ghee that is certified to be free of casein.
Make Your Own
If you are allergic, buy ghee that is certified gluten-free. If you are not allergic, you can make your own without any problems, as long as you can tolerate trace amounts of milk protein. Making ghee is relatively easy. Put 1 lb. of unsalted butter in a pan. Melt the butter and gently heat it until it comes to a boil. Heat at moderate intensity, uncovered, for about 15 minutes, or until it turns to a clear and golden color. Curds containing the traces of milk protein found in butter will form at the bottom of the pan. Pour the golden liquid through a fine sieve or cheesecloth and let it cool.
You can keep your ghee at room temperature or in the fridge. Ghee is more stable than butter when heated at high temperatures. Butter can burn because of the milk protein it contains, but by removing most of these proteins from ghee, it can be heated without burning. Use ghee to saute your vegetables, cook meat, chicken or fish or to fry rice.
