Refreshing Lemon Tart from Jacques Genin

On a hot summer day, there are few things that can just quench your thirst like a French lemon tart (or tart au citron). In Paris when the summer temperatures soar beyond what is bearable coupled with congestion from tourists, traffic, or general city heat, when I see a lemon tart I go all in. Any self respecting patisserie in the city will have these on offer. Pierre Herme is highly regarded as having one of the best in all of Paris, and rightfully so. But with all due respect, whenever I’m in the Marais, I run to patisserie Jacques Genin for what I consider the best in Paris, if not all of France.

lemon tartWhile Jacques Genin uses limes (citrons vert) in his lemon tart, it doesn’t quite taste like the limes we’re used to getting in a North American grocery. A bit more sweet, and a bit less tart, its more reminiscent of a key lime filling. When trying to recreate this recipe I found that key limes reproduced the flavour perfectly. In places where key limes aren’t as readily available, I found that using a 50/50 blend of lime juice and lemon juice worked best. If you’re in Europe and have access to limes from the south of France by all means make this recipe using lime.

For the sweet crust pastry I use Jacques Genin’s recipe with a few modifications to suit North American type flour. If you’re in Europe use T55 or all purpose flour. In North America, bread flour yields the best crumb if you like your crusts with a bit more chew. For a crispier, sandier crust stick with all purpose flour

Lemon Tart (Tart au Citron) makes 4×4″ tarts or 1×9″ tarts

Sweet Dough

125 g butter, softened

85 g icing sugar

30 g almond flour

55 g whole egg (1 egg)

1 tsp of vanilla extract or 1/2 vanilla pod

2 g salt

220 g bread flour

Lemon Filling

110 g eggs (about 2)

110 g caster sugar

55 g lime juice

55 g lemon juice

15 g lemon zest

150 g butter

To prepare the dough:

1. Cream butter, sugar and almond flour until creamy and pale. Scrape down sides of bowl while mixing to fully incorporate

2. Add egg, vanilla and salt. Mix until well combined. Scraping down bowl once to avoid clumps

3. Add flour. Mix on low just until combined

4. Wrap in plastic and refrigerate for at least an hour. For best results at least 4 hours or overnight

5. When ready to bake roll out dough between two sheets of parchment or a floured surface to around 1/4″ thick. Refrigerate 15 minutes. Cut out circles one inch larger than that of your tart ring. Line ring, taking care to make the pastry fit snugly around the edges. Refrigerate again 15 minutes and preheat oven to 350F.

6. Cut out circles of parchment again one inch larger than that of your tart ring and crumple.

7. Trim edges flush with the top of your ring. Line with crumpled parchment and fill with pie weights, or baking beans or lentils

8. Bake tarts for 15 minutes and remove pie weights. Bake for another 10-15 minutes or until golden brown.

9. Let come to room temperature then refrigerate.

For Lemon Cream

1. Bring a saucepan full of water to a boil. Lower heat to a simmer

2. In a bowl combine eggs and sugar and whisk quickly to avoid your sugar burning your eggs. Once combined add in juice and zest and cook over the saucepan to create a double boiler. Whisk until the mixture is slightly foamy. Keep whisking periodically ensure even cooking.

3. Once mixture has stopped foaming and has thickened, add in butter. Take off heat and whisk in to incorporate. Pour into a small bowl and refrigerate for a few hours.

4. When you are ready to fill your tarts, scoop lemon cream into a piping bag (no tip required) and fill almost to the top.

5. Freeze for at least 20 minutes, then let the tart come back to room temperature

  1. Hi! I am not sure when/how I came across your blog, but I must stay that this tart looks amazing! More and more I tend to go for citrus desserts – and will have to add this one to my “make soon” list.


  2. Just wondering. I want to make the lemon filling firm, as firm as possible while still remaining authentic.
    I want to replace the butter in the filling, can it be done with corn-starch and maybe some Agar-Agar gelatine? Its not a big problem if the result is not 100% accurate, as long as I can replace the big amount of butter with something that adds the right texture and firmness to the filling. Thanx.

    • You can definitely add some cornstarch. I’ve sometimes added a couple tablespoons of agar or gelatin but I wouldn’t necessarily remove a lot of the butter. Some yes but the butter also gives the curd texture that you wouldn’t get with the addition of just a binding agent. Hope this helps

      • Thanx. I know its usually not a good idea to substitute the butter, but its a LOT of butter in a cake like that for me. I will try with a bit of cornstarch to make it firm. I will try to remove 33% of the butter 🙂
