Key Lime Hibiscus Tart – So Bright and Refreshing

A key lime hibiscus tart may sound a little out of the ordinary dessert. However, it’s easy to make and brings a nice tropical feel to the party.

We have a new line of grocery stores in the area called Fresh Thyme Farmer’s Market. They appear to be a cross between Whole Foods and Trader Joes. I found a whole bag of key limes there, and since my husband is a big fan of key lime pie, I thought I’d make one for him.

Key limes are smaller than a standard lime, and they have a thinner yellowish green toned skin. Some say the flavor of a key lime is more tart and that they have an herbal or floral aroma.

Since I had an abundance of hibiscus simple syrup left over from the Hibiscus Margaritas, I wanted to try combining the two tart and tangy flavors in one dessert. 

The hibiscus syrup is a beautiful dark red.  You can make your own by infusing dried hibiscus flowers in a simple syrup made from water and sugar.

The resulting color from combining the key lime juice, sweetened condensed milk, and hibiscus syrup was a pretty peach custard. 

I also added some of the hibiscus syrup to the whipped cream. The color was more of a lavender than a pink.

I still think it looks pretty nice. And, it tastes great too.
