A "Quick" Vegetable gratin

Vegetable gratins are full of pitfalls. The vegetables cook unevenly, there is too much liquid so they end up sloppy, toppings are uneven..

So to overcome these we need to think about cooking in "layers" or stages. This recipe details the stages and techniques.

Ingredients

1 Medium Italian eggplant (aubergine), peeled in stripes and cut into 1/2" thick rounds

1/4 Cup extra virgin olive oil (divided use)

1 Tbs Aleppo pepper

2 Medium yellow onions coarsely diced

1 Red bell pepper cut into 1/2" pieces

1 1/12 lbs cherry tomatoes

1 Russet potato (coarsely grated - lke for hashbrowns)

4 Oz Melty hard chese (Cheddar/Gruyere) grated

Salt/Pepper to taste

Finely chopped chives for garnish/decoration

Method

Preheat the oven to 425F (Fan). Rack in the middle

Microwave the eggplant slices until they are soft and much of the water has been driven off. Meanwhile lighly oil a gratin dish.

Seperately saute the onions and red pepper using a little oil, Aleppo pepper, and salt ad pepper. The onions should become translucent, but not browned.

Place the eggplant slices in a single layer in the bottom of the gratin dish. 

Rinse the grated potatoes to remove the surface starch. Microwave the grated potatoes to mostly cook and dry off as much water as possible. 

Meanwhile, cover the eggplant with the sauteed onions/peppers. Sprinkle the tomatoes over the onions. Place the gratin dish into the oven, uncovered, for about 20 minutes. This will cause the tomatoes to wrinkle and soften.

MIx the grated potatoes with the grated cheese. Salt the gratin and then cover with the grated potato/cheese.

Return to the oven and cook until the internal temperature of the gratin reaches 200F.

Switch the oven to broil, and brown the potato/cheese topping until it is nice and crunchy. Sprinkle the gratin with the chopped chives.

Serve with a crisp dry wine and a side salad

Experiments with dough

I have long wondered about what happens when you make really high hydration doughs. Two events inspired me. One was the excellent cold "pizza" sold here in the Dallas area by Popolo Reds - a focaccia style bread with an intense red sauce topping. The other was an episode of Milk Street, where Christopher Kimball mae a "pizza" with a high hydration dough. Because I like to tinker, I though I would mess with some ideas and see what happens.

The key to all of this was using a very wet dough (anything up to 100% hydration) and working the dough hard. Because it almost a batter, rather than a normal bread dough, I decided to use the paddle beater in my stand mixer and not the dough hook.

I found that following the Milk Street version, the tomatoes really didn't cook enough, so I modified that recipe by roasting the cut tomatoes for 15 minutes before topping the dough and baking.

I ended up making 2 different kinds - both of which still need some tweaking for the toppings. But I am very happy with the technique. So thank you to Bob Shema and Christopher Kimball for the inspirations.

Ingredients - Dough

600 gm Bread flour

600 gm Water at room temperature

8 gm Active dry yeast

13 gm salt ( i make this a little saltier than the usual 2%)

30 gm Extra virgin olive oil (divided use) - rough measure

Method - Dough Preparation

Put the flout into the bowl of the stand mixed, with the paddle beater attachment. Activate the yeast by adding to the water. If you use instant or bread yeast, this step is unnecessary - the yeast can be added directly to the flour. Add the salt to the flour and mix thoroughly. Gradually add the water and oil while mixing slowly. Once the water is all added, increase the speed of the mixing to medium. The dough will look awful for a long while (10 + minutes). Then it will start to come together and leave the sides of the bowl. Once it has left the sides, continue mixing for 10 more minutes. It should be smooth by now, and fully kneaded.

Leave the dough in the bowl, and cover to rise. Anything up to 2 hours depending on kitchen temperature. 

Once it has risen, gently degas it by oiling your fingers and running your fingers around the bowl releasing the dough. It will sink.

Once you have degassed the dough, cover again and place the bowl in the refrigerator. Leave the dough in the refrigerator overnight

When you are ready to bake, remove the bowl from the refrigerator. Tip the dough into two oiled 1/4 sheet pans and spread it as best you can into the corners. The dough will shrink back, but that is OK. It will sit in the pan for a while and gradually spread. When working the dough, always oil your fingers. The dough is incredibly sticky. The oil will help prevent sticking.

Ingredients - Topping 1

I of the 1/4 sheet pans of dough (above)

16 oz  (450 gm) Cherry tomatoes (Note the switch to imperial measurements - that's how things are sold in the USA for the most part)

16 oz (450 gm) Sweet seedless black grapes

2 tsp Dried oregano

1 tsp Kosher salt

1 tsp Black pepper (coarse grind, fresh)

2 tsp Aleppo pepper

Oil to drizzle

Method - Topping1

When the dough has warmed to room temperature (an hour or so after coming out of the refrigerator), stud it in rows with the cherry tomatoes and grapes. Push the tomatoes ad grapes into the dough. Preheat the ovent to 450F (with fan assist).

Sprinkle the tomatoes/grapes evenly with the organo, salt, pepper, Apeppo pepper, and some olive oil. Allow the dough to puff up around the tomatoes/grapes. Once the dough has puffed up, put the pan into the preheatedoven. Turn the heat down to 400F and bake for around 30 minutes.

Slide the focaccia out of the ban onto a cutting board and allow to cool for a few minutes before cutting. Eat hot or at room temperature.

Ingredients - Topping 2

1 of the 1/4 sheet pans of dough (above)

16 oz (450 gm) Cherry tomatoes

16 oz (450 gm) mushrooms

12 sprigs Thyme

2Tbs Unsalted butter

2tsp Kosher salt (divided)

1 tsp Black pepper (coarse grind, fresh)

Oil to drizzle

Method - Topping 2

Slice the mushrooms. Microwave for a few minutes to drive off the moisture. Mix the thyme leaves into the mushrooms, add the butter, half the salt. Microwave again until the butter is incorprated.

Decorate the dough with rows of cherrytomatoes and mushrooms (as above).

Proceed withthe baking and serving as above.
