The Secret to a Great Summer Tart

A good tart needs a balance of flavors. The crust should be salty and buttery. The filling should be sour enough to make your tongue tingle but sweet enough to enjoy. I have made many tarts that were too soft or too sour. This version is just right. It uses real lemon juice and a bit of heavy cream to make it extra smooth. It is the perfect end to a backyard BBQ or a sunny lunch.

The Shortbread Crust Ingredients

To make a great crust, you only need a few items. You probably have most of these in your kitchen right now. The base of this tart is like a big shortbread cookie. It is crunchy and holds up well under the heavy cream. I like using butter that is very cold. Cold butter makes the crust flaky instead of tough. If your kitchen is hot, keep the butter in the fridge until the very last second.

• 1.5 cups of all-purpose flour
• 0.5 cup of powdered sugar
• 0.75 cup of cold salted butter (cut into small cubes)
• 1 large egg yolk
• 1 tablespoon of cold water

Using powdered sugar instead of regular sugar is a little trick I learned. It makes the crust melt in your mouth. Regular sugar can sometimes make the dough feel grainy. If you only have unsalted butter, just add a tiny bit of salt to the flour. This crust is the foundation of the whole dessert, so we want it to be strong and tasty.

Mixing and Baking the Base

First, turn your oven to 350 degrees. Put the flour and sugar in a big bowl. Use your fingers or a fork to rub the cold butter into the flour. You want it to look like coarse crumbs. My first time doing this, I melted the butter by mistake. The crust came out oily and hard. Do not do that! Keep those butter chunks small and cold. Once it looks like crumbs, add the egg yolk and water.

Mix it until a ball of dough forms. Press this dough into your tart pan. Make sure you push it up the sides too. Poke some holes in the bottom with a fork so it does not puff up like a balloon. Bake it for about 15 to 20 minutes. It should look light gold. Let it cool all the way down before you even think about the filling. A hot crust will melt your lemon cream, and that would be a sad mess.

What You Need for the Lemon Filling

The filling is where the magic happens. It is basically a mix of homemade lemon curd and whipped cream. This makes it lighter than a standard tart. You will need a lot of lemons. Fresh juice is much better than the stuff in a green plastic bottle. IMO, the bottled juice tastes like chemicals. Fresh lemons have a zing that really wakes up your taste buds. I usually buy a big bag of lemons at the store just to be safe.

• 1 cup of fresh lemon juice (about 5-6 lemons)
• 1 tablespoon of lemon zest (the yellow skin)
• 1 cup of white sugar
• 4 large eggs
• 1 cup of heavy whipping cream
• 1 teaspoon of vanilla extract

The zest is important because it holds all the lemon oil. That oil has the most flavor. When you grate the lemons, stop when you hit the white part. The white part is called the pith, and it is very bitter. You only want the bright yellow skin. Mixing the eggs and sugar first helps the filling stay smooth and yellow. It looks like sunshine in a bowl when you finish mixing it.

Cooking the Lemon Curd

Put the lemon juice, zest, sugar, and eggs in a small pot. Turn the heat to medium-low. You must stir this the whole time. If you stop stirring, the eggs might cook too fast and turn into scrambled eggs. I did that once, and I had to throw the whole batch away! It was a big waste of lemons. If you see little white chunks, your heat is too high. Slow and steady is the way to go for a smooth cream.

Keep stirring for about 8 to 10 minutes. The mix will start to get thick. It should look like pudding or thick gravy. Once it coats the back of your spoon, take it off the heat. Pour it through a fine strainer into a bowl. This catches any bits of egg or zest so the tart is perfectly smooth. Cover the bowl with plastic wrap. Make sure the wrap touches the top of the lemon cream so a skin does not form. Put it in the fridge to get cold.

Folding in the Whipped Cream

Now we make it airy. Whip your heavy cream in a separate bowl until it is stiff. You want it to stand up in peaks when you lift the whisk. Once the lemon curd is totally cold, gently stir in the whipped cream. Do not stir too fast! If you are too rough, you will pop all the tiny air bubbles. We want the filling to be like a cloud. I use a big spatula and move it in a circle, folding the bottom over the top.

This is my favorite part because you can see the colors marble together. It turns into a beautiful pale yellow. Taste a little bit now. It should be creamy but still very tart. If you feel it needs more sweetness, you can fold in a tiny bit more powdered sugar. This filling is very forgiving. Just remember that it needs to stay cold to keep its shape. Once it is mixed, pour it into your cooled tart crust and smooth out the top with a knife.

The Best Way to Decorate

A plain yellow tart is fine, but we want it to look great. I like to use thin slices of lemon and fresh mint. The green and yellow look so good together. You could also use fresh berries. Raspberries or blueberries go very well with lemon. If you want to be fancy, you can pipe extra whipped cream around the edges. Just make sure you do the decorating right before you serve it so the fruit stays fresh.

I learned a lesson about decorating too early. I once put mint leaves on a tart the night before. By the next morning, the mint was black and wilted. It looked like old grass. Now, I always wait until the guests are almost there. If you use berries, make sure they are dry. If they are wet, the juice will bleed into your beautiful yellow cream and make it look messy. Keep it simple and clean for the best look.

How to Slice and Serve

To get a perfect slice, use a hot knife. Run your knife under hot water, wipe it dry, and then cut. The heat helps the knife glide through the cold cream without sticking. Wipe the knife after every single cut. It sounds like a lot of work, but it makes the slices look like they are from a magazine. Serve it cold right out of the fridge. On a hot summer day, this tart is the best thing you can eat.

This tart is great on its own, but you can serve it with a side of vanilla ice cream if you want. Some people like a cup of tea or a cold glass of lemonade. FYI, this tart is very rich, so you only need a small slice. It serves about 8 to 10 people easily. If you have leftovers, they will keep for a day or two, but the crust might get a little soft. It is always best on the day you make it.

Making this tart is a fun weekend project. It does not use fancy tools, just a stove and a bowl. You will feel so proud when you take that first bite. It is much better than anything you can buy at the grocery store. Plus, you know exactly what is inside of it.

Your Questions Answered

Sometimes things go wrong in the kitchen. Don’t worry! Here are some common questions I get about this recipe. These should help you fix any problems before they happen.

Can I use a store-bought crust?

Yes! You can use a pre-made graham cracker crust if you are in a rush. It will still taste great with the lemon filling.

Why is my filling runny?

You may not have cooked the lemon curd long enough. It needs to be thick like pudding before you cool it down.

Can I make this tart dairy-free?

It is hard because of the butter and cream. You can try coconut cream, but it will change the flavor a lot.

How long does it stay fresh?

It stays good for 2 days in the fridge. After that, the crust gets soft and soggy from the lemon cream.

My crust broke, what do I do?

Don’t panic! Just press the broken pieces back together while it is still warm. The filling will hide the cracks anyway.

Enjoy Your Summer Treat

This lemon cream tart is the ultimate summer dessert. It is bright, cool, and very tasty. I hope you enjoy making it as much as I do. Remember to keep things cold and be patient with the stirring. You are going to do a great job!
