Preheat the steamer on medium heat.
In a mixing bowl, add curry paste and just enough coconut milk to dissolve the paste, whisk until smooth. Add the remaining coconut milk, eggs, palm sugar, fish sauce, and kaffir lime leaves; whisk in the same direction without lifting the whisk (this is to avoid whisking in too much air) until the eggs are well combined with the liquid. Add the fish into the custard.At this point, if it's your first time you want to check the seasoning as different brands of curry paste are not equally salty. Put a small amount of the liquid into a heatproof bowl and steam or microwave briefly until cooked. Taste and add more fish sauce if needed. 3 tablespoon red curry paste, 1 ¼ cup coconut milk, 1 tablespoon palm sugar, 2 teaspoon fish sauce, 2 large eggs, 3 makrut lime leaves, 5.6 oz any kind of fish filet
Prep the ramekins: If using banana leaves, measure the length of your ramekin from one edge to the other, and cut a strip of banana leaf along the grain to that length, and make strips just wide enough that it sits flat on the bottom. Wipe clean with a damp cloth. Line the ramekin with one strip, and place the other perpendicular to the first strip.
Banana leaves
Place the cabbage and/or kale into a heatproof bowl and steam it for 3-5 minutes until wilted. Divide the cabbage amongst the ramekins, then add 2-3 Thai basil leaves to each ramekin.
1 ½ cups shredded cabbage and/or kale, 8-12 leaves Thai basil
Distribute the fish evenly into each ramekin, then fill the ramekin with the custard, leaving about ½ inch of headroom.
Place the ramekins into the steamer and steam over medium heat for 15-20 minutes or until set. The larger your ramekin, the longer it will take.
While the custard steams, make the garnish. Put cornstarch into a small pot then add a splash of water and stir just until it's all dissolved. Add the coconut milk and stir to mix. Cook over medium high heat, stirring constantly, until it boils and is thickened. Remove from heat and pour into a small bowl; it'll thicken further as it cools
½ teaspoon cornstarch, ¼ cup coconut milk
When the custard is done, it will be puffed up and will not jiggle much when shaken. To serve, spoon a little of the thickened coconut on top, then garnish with cilantro leaves and red chilies. Serve with jasmine rice.
