Cauliflower Egg Walnut Gratin

A creamy sauce flavored with turmeric and tarragon makes a smooth, warming gratin.  Cauliflower and egg are a natural combo, for texture, flavor and protein. A crispy walnut topping gives a crispy contrast to each succulent bite.


1 small head cauliflower, cut into flowerets
1 medium onion (tennis ball sized), sliced
3 oz grated or finely cubed cheddar cheese (or favorite)
4 eggs

Sauce:
1/4 cup four
2 Tbsp butter plus 1 Tbsp canola oil
2 cups milk
2 Tbsp fresh tarragon leaves
1/4 tsp crushed red pepper flakes, or to taste
1/2 tsp powdered turmeric

Topping:
2 Tbsp shelled walnuts
2 Tbsp panko bread crumbs
1 clove garlic
2 tsp olive oil

Preheat oven to 375F.  Bring a medium pot of water to boil.  Add the eggs and return to the boil.  Remove eggs from the heat, cover and allow to stand 10 minutes.

Meanwhile prepare the sauce by melting the butter in the oil in a small sauce pan.  Add the flour and cook until bubbling and beginning to brown, about 2-3 minutes.  Add the tarragon and pepper flakes and turmeric.  Whisk in the milk.  Bring to a gentle boil, whisking often, as the sauce thickens.  
When thickened, season with a dash of salt and pepper to taste and set aside, covered.

Remove the eggs from the water with a slotted spoon after 10 minutes. Plunge in cold water and allow to cool enough to handle.  Peel and coarsely chop the eggs.

Return the water to a boil.  Salt generously and add the cauliflower and onion.  
Bring to a gentle boil and cook just until the onion is softened and the cauliflower is still crisp-tender.  Drain cauliflower.

Meanwhile, pulse the walnuts, bread crumbs and garlic in a small food processor to form a coarse meal.  Toss the topping with the oil.

Oil a medium casserole and lay one third of the sauce on the bottom.  Top with half the cauliflower, egg and cheese.  
Top with another third of sauce.  Finally top with remaining cauliflower, egg and cheese.  Top casserole with remaining sauce and sprinkle the topping over all.
Cover with aluminum foil and bake 20 minutes.  Remove the foil and bake another 10 minutes to brown.
Serves 4.

Umami Beef Short Ribs Samin Nosrat

This is the penultimate prep for beef short ribs.  Based on the superb documentary by Samin Nosrat, Salt, Fat, Acid, Heat, this is the most umami rib dish you will ever have.  Its the combination of red miso and soy sauce that marinates and flavors the beef - give it a long time to work right - that means overnight in the fridge; it's worth the planning ahead. 6 beef short ribs on the bone, about 3-4 lb 1 large sweet yellow onion, diced 2 stalks celery, diced 1 jalapeño pepper, minced 4 cloves garlic, halved Marinade: 1/4 cup red miso 1/4 cup soy sauce 1/4 cup pale dry sherry or Mirin rice wine 1 Tbsp sesame oil 1 Tbsp honey 2 cloves garlic, minced Salt the ribs generously with coarse salt and let rest overnight in the refrigerator in a resealable plastic bag. Whisk together the marinade.   Pour into the plastic bag and allow to marinate on the counter for about 2-3 hours, or again overnight in the refrigerator. Preheat...

Vinaigrette Erique 2.0

From the archives:  Making a really, really good vinaigrette has been a craft in my family, and in my in-law family for generations. My late uncle, Jeannot, and Father-in-law, Bernard, (both best of friends) were each geniuses at the vinaigrette. And they both taught me. I have to say my siblings along with my sisters and brothers in-law do really now carry on the tradition as I strive to as well.  In our family cookbook "Cuisine Encore" I published my go-to vinaigrette - a basic version taught to me by my French mother, Monique.  It's great, yet I have been looking for something slightly more modern and upbeat.  So I merged Asian rice vinegar into the mix along with fresh (not powdered) garlic with the Dijon mustard, and toned down the salt. Make it your own. I now have what I think is an even better basic vinaigrette, today. Talk to you tomorrow! 1/4 cup cider vinegar 1/4 cup seasoned rice vinegar 1 generous tsp Dijon mustard 1/2 tsp salt 1/2 cup ca...

Rosemary Chimichurri

I am making this fresh aromatic condiment more and more often. It can be used as a topping for grilled meats, fish, and for many other flavoring opportunities. I now keep some in the refrigerator almost at all times. 4 Tbsp fresh rosemary leaves large palmful fresh cilantro, leaves and stems 3 cloves garlic 1/2 tsp crushed red pepper flakes juice of 1/2 lime (or lemon), and the zest if you like 1/4 tsp salt fresh ground black pepper to taste 1/4 cup olive oil Pulse the rosemary, cilantro and garlic in a small food processor (You could also use a mortar and pestle.) Tip into a small bowl and stir in the remaining ingredients. Cook’s Note: If you haven’t noticed, I love chimichurri sauce.   It’s zesty, and full of aromatics. It goes on so many dishes and is a great ingredient for so many things.   Make some and keep it in the fridge for inspiration. I use fresh rosemary and cilantro as my green herbs, but you could use oregano and parsley, which is also popular.   Many peo...
