Instructions
Cut eggplant into thick rounds. Salt them evenly. Wait 15 minutes. Wipe off the water.
💡 Control the eggplant water
Salt draws out water through osmosis in 15 minutes. This prevents a soggy texture. It stops heavy oil absorption.
Salt the eggplant first. Wipe it dry.
Does this step really matter?
Yes. It removes bitter water and stops oil soaking.
Heat olive oil in a pan. Sear the eggplant slices. Cook until golden brown.
💡 The Maillard reaction matters
High heat changes surface proteins at 150C. This creates complex savory flavors. Never skip this browning step.
Do I have to cook them fully here?
No. Just sear the surface. The oven will finish cooking them.
I see. We just want the flavor crust.
Dice the fruit tomatoes. Simmer them slowly. Add soy sauce and miso cheese.
💡 Umami synergy explained
Tomatoes have high glutamic acid. Soy sauce adds fermented aminos. Together they multiply the savory taste by 7 times.
Why soy sauce in a gratin?
It acts as a secret umami booster. It connects the tomato and cheese.
A true Japanese and Western blend!
Layer the seared eggplant and tomato sauce. Top with lots of cheese. Bake until bubbly.
FAQ
Why is my gratin so watery at the bottom?
You likely skipped salting the eggplant. Salt draws out water before cooking. Always wipe the eggplant completely dry before searing.
Can I use different vegetables for this dish?
Yes. Zucchini or bell peppers work beautifully. Just make sure to sear them first. Searing removes extra moisture and builds flavor.
The cheese on top is burning too fast. What should I do?
Lower your oven rack slightly. You can loosely cover the top with foil. Remove the foil during the last few minutes.
Why add Japanese soy sauce to a Western tomato dish?
Soy sauce adds incredible deep umami. It acts as a natural flavor enhancer. It makes the tomato flavor taste much more complex.
