Creating the Spring Radish & Butter Crust Torte is simple when you follow these easy steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Make the Dough: In a large bowl, combine flour and salt. Add chilled butter and mix until the mixture resembles coarse crumbs. Gradually add ice water, one tablespoon at a time, mixing until the dough forms a ball.
3. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for about 15 minutes.
4. Prepare Radishes: In a medium bowl, toss the sliced radishes with olive oil, lemon juice, salt, and pepper. Set aside to marinate.
5. Roll Out Dough: On a floured surface, roll out the chilled dough to fit a 9-inch tart pan. Press the dough into the pan and trim any excess.
6. Pre-bake the Crust: Place parchment paper over the crust and fill with pie weights or dried beans. Bake in the preheated oven for 10-12 minutes. Remove the weights and parchment paper, then bake for an additional 5-7 minutes until lightly golden.
7. Prepare Filling: In a bowl, whisk together eggs, heavy cream, and Dijon mustard until smooth. Season with salt and pepper.
8. Assemble Torte: Spread the marinated radishes evenly over the pre-baked crust. Pour the egg and cream mixture over the radishes.
9. Bake the Torte: Return the torte to the oven and bake for 25-30 minutes or until the filling is set and lightly golden on top.
10. Cool: Remove from the oven and let the torte cool for at least 15 minutes before serving.
