There’s just something incredibly refreshing about pineapple tarts with their tangy, bright, acidic flavor nestled in shortbread crusts. Adding meringue puts a tropical twist on the classic meringue pie making them a perfect summer treat.
When it comes to making meringue, simple ingredients and instructions can lull you into thinking preparation is quick and easy. Make it once under the wrong conditions, however, and you may quickly change your mind.
Meringue is temperamental. Getting it right can be a tricky process. Weeping meringues aren’t very pretty. The meringue pulls back from the crust, moisture beads on the topping, and a clear liquid forms below the crust. It doesn’t hurt the pie but it’s not presentable.
Years ago, when I worked in the commercial food industry, I started using the idea of adding cornstarch to meringue to help stabilize it. Cornstarch is especially helpful in hot, humid weather when a meringue is most likely to absorb extra moisture.
The science behind this ‘secret ingredient‘ is that cornstarch is composed of long molecules that it is believed insert themselves between egg white proteins to prevent them from clotting too much while meringue is baking. Corn starch molecules also provide more hold for meringue. It will be easier to cut and is less likely to weep.
Brion & I are not crazy about meringue but do enjoy it for a treat once in a while.
