### The Science Behind Cauliflower Gratin
Blanching cauliflower before adding it to the gratin ensures even cooking throughout the dish. By seasoning the mornay sauce with white miso paste, we enhance the flavors of Gruyère and Parmigiano-Reggiano, introducing a subtle sweetness and nuttiness. The addition of za’atar in the breadcrumb topping provides a bright contrast to the rich cheese and cream, balancing out the overall flavor profile.
My journey with cauliflower gratin began during a frigid Cincinnati winter. Having moved from India, where winters are warm and inviting, I found myself battling biting winds and snow-covered streets in my new Midwestern home. Seeking solace from the cold, I often retreated to libraries and bookstores. It was there that I discovered Jane Grigson’s Vegetable Book featuring a recipe for cauliflower gratin—a dish that quickly became my comfort food of choice. The combination of tender cauliflower enveloped in a savory mornay sauce topped with buttery breadcrumbs was irresistible.
Though I’ve since left Cincinnati behind, this dish remains close to my heart. Over time, I’ve adapted it to suit my tastes while preserving its essence. My version emphasizes sweet and nutty cheese flavors: tender cauliflower florets are smothered in a creamy mornay sauce made from semi-firm cheeses like Swiss or Gruyère before being crowned with crispy breadcrumbs enhanced by miso paste for an extra layer of umami.
### Preparing Cauliflower for Gratin
To achieve an evenly cooked gratin, it’s crucial to prepare your cauliflower properly first—this leads us to consider whether blanching is necessary or if steaming will suffice. After testing both methods side-by-side, I found that while oven-steamed cauliflower wasn’t significantly more flavorful than blanched ones nor faster (taking 25-30 minutes compared to about 10 minutes for blanching), blanching proved more efficient overall.
Crafting Mornay Sauce
Creating an exceptional mornay sauce hinges on understanding how roux—a mixture of fat and flour—thickens sauces effectively. To make roux: whisk flour into melted butter until combined; cook briefly until raw flour taste dissipates without darkening too much (as darker roux yields thinner sauces). This technique not only enhances flavor but also prevents clumping when you add liquid like milk or stock later on.
The type of starch (flour) used along with fat influences both flavor and thickness; thus we aim for a thick yet pourable consistency here using equal parts flour and butter as our base before incorporating milk enriched by Gruyère’s creaminess.
Elevating Flavor with Umami
To amplify savory notes within our sauce further still—white miso paste is added! This ingredient intensifies cheesy flavors while contributing its own unique nuttiness thanks largely due fermentation processes transforming proteins into umami-rich amino acids through koji mold action on soybeans—a culinary marvel indeed! Combined alongside glutamate-rich seasonings such as onion powder & garlic powder results in complex layers enhancing natural sweetness present within our beloved vegetable star: cauliflower!
Seasoning Breadcrumbs
While it’s possible to enjoy gratin sans crunchy breadcrumb topping—it wouldn’t be quite as delightful! For mine? A sprinkle of za’atar adds depth & brightness against all that creamy richness at play here! Za’atar refers both specifically plant indigenous primarily around Levant region plus spice blend derived thereof; though sourcing fresh varieties may prove challenging stateside—substituting oregano works well enough if making your own mix!
