This was an exercise in overcoming failures in the kitchen. In the end, I saved the pie.First, I tried to put my twist on the dessert by candying some shaved lime peels. They came out like sugar coated rubber strips.Next, the whipped cream. It didn't whip. I was using light cream. If you freeze a stainless steel bowl, pour in the cream, even low fat cream should whip. It didn't. It did however triple in volume though it never got to the soft peak stage.I remixed the milk, lime and cream with a hand mixer on high. The pie did set up after about 3 hours in the refrigerator.I tried freezing it as well and the result is what I would call, an "ice box" cake. The texture of the frozen cream filling was very good.Refrigerated or frozen, give it a try.1 store bought graham cracker lined pie plate1 14 ounce can light, sweetened, condensed milk1/2 cup lime juice (4 to 5 limes)Lime zest from 1 lime1 cup light creamWash the limes. Juice enough limes until you have 1/2 cup.
Zest a lime with a microplane or the use finest openings on a box grater. Add to the condensed milk. Add the lime juice.
Mix the condensed milk, lime juice and zest on high until slightly fluffy.
Whip the cream and add to the milk and lime mixture. Mix on high again for 2 minutes.
Pour into the pie crust.
Refrigerate for at least 3 hours so it sets up. Alternatively, you can freeze the pie to make a frozen dessert.
Decorate with lime pieces.
What kind of potato? The new potatoes below worked well. Normally you would peel the potato, but the thin skin on the new potato (I think it might be a baby Russet) means peeling them is optional.I did peel the carrot before grating. I also peeled the fibrous outer layer on the celery.4 medium new potatoes - about 1-1/4 pounds - cut into bite-sized pieces1/4 cup of white vinegar2 hard boiled eggs, chopped1 rib of celery, diced small1/3 of a large carrot, grated3 heaping tablespoons of light mayonnaise1 heaping tablespoon of bright, green, sweet relish1/2 teaspoon of celery seed1/2 teaspoon of fresh ground black pepper1 pinch of kosher salt if needed1 gallon of well salted water in a pot for boiling the potatoes
Cut the potatoes in half length-wise. Cut the halves in half length-wise.
Slice into bite sized pieces.
Boil the sliced potatoes in the salty water for 25 minutes or until tender.While boiling, grate the carrot. Finely chop the celery. Peel and chop the hard boiled eggs.Drain the water and potatoes into a colander. While still hot, sprinkle the white vinegar on the potatoes while still in the colander. Transfer to a big bowl.Add all the other ingredients and gently fold the mixture well with a rubber spatula.

The white vinegar adds a crisp punch of acid. I like it best for this recipe.The "secret" ingredients in this recipe are the celery seed and sweet relish.Variations:
- Substitute apple cider vinegar
- Add chopped, crispy bacon or finely chopped ham
- Add hot sauce
- Substitute sour cream for the mayonnaise
- Add finely chopped red onion or shallots
It's important to sprinkle on the vinegar while the potatoes are still hot so they absorb the flavor.If the sliced potatoes are cooked in well salted water, you should not need salt for this recipe. Possibly, you may want to add a pinch to the final product based on taste.This recipe makes 8-10 servings at about .25 cents per serving.
