Tab Tim Grob- Thai Sweet Coconut and Water Chestnut Desert
Tab Tim Grob is a Thai dessert that literally translates to crunchy red rubies. This recipe can be pronounced and made a variety of ways, but the main theme is usually the same. It is always some form of crunchy little jewels in coconut milk with ice. In our recipe, my wife Mod made the water chestnuts heart-shaped for Valentine's Day.
I came across several other food blogs that have done it in different, beautiful ways, When I was looking for a bit of history on the recipe. Your imagination is the limit with these fun recipe. We did it with corn as well for a variation you might commonly see in Thailand as well.
The food network went for a darker red by using food coloring which we shy away from. Amita did it with beautiful green and purple colors at her blog amitathaicooking.com. For our recipe, Mod grated beet and used it to color the water chestnut.
If you google it, you will notice different spellings as well. The Thai looks like this ทับทิมกรอบ. You can imagine how with so many different sounds, making an English version would be a bit tricky. You may see it written as thaptim krop or tab tim krop as well and who can really say which is right?
