Preheat the oven to 190 C / 370 F and prepare a large baking tray lined with parchment paper.
Wash and dry the aubergines.
If you’re using thinner varieties like Chinese or Japanese Aubergines, halve them lengthways first and then cut each half in half to create quarters. This helps them cook more evenly.If you’re using large aubergines, simply halve them lengthways and place flesh side up on the lined baking tray. With a sharp knife, score the flesh of the aubergines in a criss-cross pattern going about halfway in. Careful not to cut through the skin.
Brush the flesh with a little olive oil or vegetable oil to prevent burning. Place the tray in the oven and bake for 10 minutes.
While baking, use a fork or small whisk to mix together the miso, ginger, cornflour, soy sauce, garlic, honey, sesame oil and mirin in a small bowl. If the sauce feels too thick, add a spoonful of hot water to thin it a little.
Remove the aubergines from the oven and generously brush all of the miso sauce evenly onto the flesh of each aubergine.
Bake for another 20-25 minutes until the sauce becomes golden brown and sticky. The flesh should be soft.
Top the aubergines with some sesame seeds, freshly chopped green onions and some cilantro if you like!
Serve with some white rice and steamed vegetables for a delicious meal.
