Yogurt turning sour is a common problem during the summer, but a small piece of coconut can completely eliminate this issue. Let’s discover a traditional home remedy that allows you to keep your homemade yogurt fresh and sweet—without it turning sour—for 10 to 15 days.
Whether it is a scorching summer afternoon or a warm night, it is simply unimaginable to have a meal without a serving of cool, refreshing yogurt on the plate. During this season, yogurt is consumed daily in households across the country. People incorporate yogurt into their diets in various forms—ranging from *raita* and *kadhi* to *lassi*. However, when it comes to setting yogurt at home, a common problem plagues almost every household: the yogurt turning sour. In the summer, yogurt that was set in the morning—initially sweet and fresh—often turns so sour by evening that it becomes nearly impossible to even taste it.
Despite being stored in the refrigerator, yogurt frequently turns sour. If you, too, are frustrated with having to discard sour yogurt every other day—or forcing yourself to consume it regardless—worry no more. By adopting a simple little trick, you can easily prevent your yogurt from turning sour. This solution involves a piece of coconut. Yes, a single piece of coconut is all it takes to keep your homemade yogurt as fresh and sweet as store-bought varieties for several days.
What is this “Coconut Trick”?
You may be hearing about this trick—adding a piece of coconut to yogurt—for the first time, but it is by no means a new trend. People have been using this method to prevent yogurt from turning sour for a very long time. In the past, before refrigerators existed, people would adopt such measures to keep their yogurt fresh for extended periods.
The very bacteria present in yogurt that help it set are also the ones that cause it to turn sour over time. However, when you add a small piece of coconut to it, it slows down this process slightly, thereby preventing the yogurt from turning sour too quickly.
How to Use It?
- If you, too, wish to prevent your yogurt from turning sour using this trick:
- First, prepare the yogurt from milk in the usual manner.
- Once the yogurt has set completely, take a fresh raw coconut and cut a 2–3 inch piece from it.
- Now, wash this piece thoroughly.
- After cleaning the piece well, gently press it down into the yogurt.
- Finally, cover the container and place it in the refrigerator.
What is the benefit?
If you add a piece of coconut to your yogurt, it will not turn sour quickly. This keeps the yogurt fresh for 10–15 days without affecting its taste.
However, when using this coconut trick, ensure that the coconut is always fresh. Dried coconut or grated coconut will not work for this method. Additionally, make sure not to repeatedly remove the piece of coconut. If you have a large quantity of yogurt, use a slightly larger piece.
