If you've never made a terrine, this is a good place for a home cook with, say, intermediate kitchen skills to start. It uses late summer vegetables, ones that your SIPs are starting to deliver. It's also a very flexible recipe. The basic technique can be used with several different combinations of vegetables.
Before I get to the terrine, I'd like to point out that there are countless recipes, and sites devoted to them, that you could use to prepare your vegetables. With good ingredients, simple is better; a plate of sliced heirloom tomatoes drizzled with olive oil, sherry vinegar, basil, salt and pepper. Add a few slices of No-Knead Bread , some good cheese and a bottle of wine and it's a meal.
If you want some more ideas, I've found two of Mark Bittman's cookbooks to be helpful--Best Recipes in the World and How to Cook Everything - Vegetarian.
Grilled Vegetable Terrine
Adapted from Michael Ruhlman's Charcuterie and this recipe on Epicurious.
2 eggplant (roughly 2 pounds), peeled and sliced lengthwise into 1/4" slices
2 zucchini (roughly 1 pound), sliced lengthwise into 1/4" slices
2 yellow squash (roughly 1 pound), sliced lengthwise into 1/4" slices
Olive oil to brush on the above prior to grilling, (or broiling)
Salt and pepper
2 or 3 sweet peppers, roasted, peeled, seeded, and cut into strips
4 or 5 oven dried tomatoes, (click here for more on this technique), or sun-dried tomatoes
8 oz. goat cheese, softened to room temp.
1/2 c. of your favorite vinaigrette
1 1/2 Tablespoons water
1 teaspoon powdered gelatin
A narrow terrine pan, 10"x3"x3". If you have a different size you'll need to adjust the quantity of your ingredients. Also, any mold wider than three inches might cause the finished product to sag in the middle.
Mandoline, optional but makes things a lot easier
Piece of cardboard cut to fit the top of the terrine pan
2 one pound cans, used to weigh down the terrine while it sets overnight
It takes about an hour of prep time, plus it needs to chill overnight
Yield: 8 to 10 appetizer portions
Slice the first three vegetables as uniformly as you can, a mandoline works best. Brush with oil, season with salt and pepper. Grill over medium heat until tender, turning just once so you get nice grill marks. Transfer to a plate to cool.
Before you start putting the terrine together, taste each of the components. If you don't like anything, change it now. It won't magically improve after being refrigerated overnight in a mold.
Put the water in a saucepan and sprinkle the gelatin over it. Once the gelatin is absorbed (blooms), put the pan over low heat until it's dissolved. Add it to 1/4 cup of the vinaigrette and keep it warm so it doesn't start to set up while you assemble the terrine. Putting the cup of vinaigrette into a slightly larger bowl of warm water does the trick.
Line the terrine with plastic wrap. You want enough overhang, (about 3 inches, on the long sides) so you can fold it over on the top of the finished terrine. Wetting the inside of the mold before you put in the plastic will make the plastic stick in the corners. Put a layer of eggplant slices in the mold first. Put them in crosswise, with the end of each piece starting at the centerline of the bottom of the mold and running up, and over, the side by an inch or two.
Keep in mind that the first layer you put down is going to be the "top" of the finished terrine, so put the pieces down with very little overlap. And that you're going to be serving a cross section of whatever you put inside the mold.
Lightly brush the eggplant with vinaigrette. You might have enough eggplant to put down two layers, overlap the joints where possible. After each layer brush with vinaigrette, it's the glue that holds the whole thing together. Repeat with the zucchini and yellow squash, remembering to put vinaigrette between each. Lay the strips of pepper in the mold and brush with vinaigrette. Gently press the goat cheese into the mold, creating an even layer and brush it with vinaigrette. Lay the tomatoes on top of the cheese, again brushing with vinaigrette. Fold the eggplant and squash flaps on top of the tomatoes, brush the top with the remaining vinaigrette. Pull the plastic up over the top and seal the terrine. Push down on the finished terrine using a little bit of pressure. You want to eliminate any voids and create a fairly solid block of vegetables. Put the cardboard cutout on top of the plastic you just sealed. Refrigerate overnight with the two weights on top.
Take it out of the fridge about a half hour before serving. Flip it over on to a cutting board, remove the plastic, turn it right side up (what was the bottom of the mold is the finished top of the terrine) and cut it into 1/2" slices. You'll get a clean slice if you use a thin bladed knife and pull it toward you with a long stroke rather than sawing back and forth. Clean off the knife in a tall glass of hot water as needed. Serve each piece with a little of the reserved vinaigrette on the side.
Try this recipe using different vegetables: carrots, mushrooms, leeks, onions, or fennel. Or boil, and shock in an ice water bath, some chard or kale to use as the outer layer instead of eggplant. You can play around with whatever combinations taste and look good. I wonder if I could make it a truly vegetarian dish by substituting agar for the gelatin? I bet someone at Ideas in Food or Playing with Fire and Water could tell me.
Rulhman's Charcuterie is discussed here on eGullet. Now that you're familiar with the basic technique, put it to use by making other terrines and patés.
