Anyone who has enjoyed a gyro sandwich can attest to the deliciously delectable dill, yogurt, and cucumber concoction known as tzatziki. The cool cucumber and tangy yogurt provide a solid base for the aromatic dill and garlic, which work and play beautifully with all manner of roasted and grilled meats, as well as the wonderful gyro sandwich.
However, anyone who has ever made tzatziki knows that there are a few potential pitfalls littered across the landscape, presenting the potential for culinary catastrophe at every turn. Many of these dangers can be avoided simply by choosing the correct ingredients, such as fresh cucumbers, Greek yogurt, young garlic, and the like. Still, danger still lurks beneath that fresh, promising exterior.
Weeping Cucumbers
As important as it is to start with the right ingredients, a good tzatziki recipe also depends on those ingredients being prepared properly before they are introduced to the final sauce. Since the bulk of the sauce is made up of yogurt and cucumbers and the yogurt has already been covered, let’s take a moment to consider the cucumbers.
Let’s say you made a wonderful tzatziki sauce for dinner. You served it on roast lamb or gyros and got rave reviews all around, but you made a little too much and had to put the rest in the refrigerator. The next day for lunch, you decide to pull it out and have a little with some pita chips, only to find a watery, nasty mess instead of the creamy sauce you made the night before. So, what happened?
Cucumbers are made up mostly of water, far more than most vegetables. As you chop, slice, or grate the cucumber for your tzatziki, the barriers holding that water in the cucumber are broken down, letting the water steadily seep out. Of course, this process, left to its own devices, takes several hours, which is why your beautiful tzatziki, over the course of a night, wept more than a man would watching Kevin Costner play catch with his father in Field of Dreams.
Avoiding Disaster
There are two potential ways to prevent this disaster from occurring, and both depend on the same simple concept: get rid of as much water as you can before introducing the cucumber to the yogurt. After all, the cucumber can’t cry into your sauce if its tears have already been spent.
The first method is called the salt-and-purge method. After chopping or grating the cucumber, toss it with a bit of salt and leave it to drain over a colander for an hour or two. The salt will pull out most of the moisture. Most people recommend about 1/4 tsp of salt or so per cucumber, and some of that gets washed away by the water as it gets pulled out.
The second, and much faster method is what I like to call the-old-Charmin-squeeze. Just wrap up your fabricated cucumber bits in a tea towel or a few layers of cheesecloth and just wring that water right out. Since this method takes a few minutes as opposed to a few hours and doesn’t add any salt to the mix, it is the one I prefer. Just be careful that you don’t wring the towel so hard that you break it, which happened the first time I tried this method.
Either way, once the water has been safely evacuated from the cucumber, it is safe to add to your yogurt to complete the recipe, which can then be enjoyed for up to a few days, as long as it stays refrigerated (if you can stay out of the bowl that long).
