Quick Info
The Balance of Light and Rich
By splitting the dairy between milk and heavy cream, we reduce the overall heaviness of the dish without sacrificing the classic French 'Migaine' texture. The addition of four egg yolks provides the necessary fat and protein to ensure a stable, velvety set.
Parisian mushrooms, when sliced and sautéed until golden, offer a familiar and elegant earthiness. Flash-toasting the cherry tomatoes before baking caramelizes their natural sugars, adding a concentrated burst of umami that complements the white miso in the custard.
Emmental offers a milder, nuttier backdrop allowing the delicate notes of nutmeg and the savory depth of the soy-glazed mushrooms to shine through.

Tips & Tricks
If the tomatoes are making the crust soggy: Flash-toast them cut-side down first. This sears the surface and locks in juices, and always place them cut-side up in the tart shell.
If you want a more intense mushroom flavor: Make sure the Parisian mushrooms are sliced and sautéed on high heat until they are deeply browned. Don't crowd the pan!
Frequently Asked Questions
Will the miso make this taste like Japanese soup?
Not at all. At just 15 grams for the whole quiche, the white miso acts as a hidden flavor enhancer—like adding a pinch of MSG or aged Parmesan.
Is this quiche very heavy?
We've swapped the heavy cream-only base for a 50/50 mix of milk and cream. This makes the quiche feel lighter on the palate, while the extra egg yolks ensure it remains incredibly silky.
