DIM SUM MONTH: Creamy salmon & egg in rice wrapper rolls

Ingredients

RICE WRAPPER/CHEUNG FUN:
• 3/4 cup + 1 1/2 tbsp (100 grams) short grain rice flour
• 1/4 cup (33 grams) potato starch
• 1 cup + 2 tbsp (267 grams) water
FILLING: (see note)
• 1 lb (500 grams) mid-cut salmon
• 1 tbsp salt
• 2 tbsp finely diced scallions
• 1 tbsp plain mayonnaise
• 1 portion 15-seconds magic scrambled eggs (3 eggs)
• fresh cilantro leaves
SWEET SOY SAUCE:
• 1/3 cup (94 grams) soy sauce
• 2 tbsp + 2 tsp (31 grams) light brown sugar
• 2 tbsp (30 grams) water

Instructions

1. This instruction differs from how restaurants typically do it, which is to always steam the cheung-fun/rice wrapper and the fillings together simultaneously, right before serving. Here, I prepare the cheung-fun/rice wrapper separately and beforehand. It gives me more control to play with the fillings, and makes them easier to prepare for a party.
2. PREPARE THE CHEUNG-FUN/RICE WRAPPER: Make the wrappers up to 4 hours before serving. Check out RICE RIBBON for more referrences. In a jar that's easy to pour, whisk together rice flour, potato starch and water.
3. For steamer, you can use any large pot with a rack placed in the middle to hold the mold/pan. I used a 6" (15 cm) square cake-pan as my mold to make the rice wrapper because 1) It fits into my steamer/pot (see photo). 2) It's just the right size for one single roll. If you have a larger steamer that can allow a bigger pan that will cut down the number of time of steaming, you can do that as well.
4. Fill the steamer/pot with enough water just below the steamer-rack, then bring to a boil over high heat. Brush the pan with a bit of canola oil and place it on top of the rack. Give the batter a little whisk (do this every time before you pour), then pour just enough batter to create a thin film on the bottom of the pan. ADJUST THE POT so that it's LEVELED, and that the batter is evenly thick on all sides. Close the lid and steam on high heat for 1 min. The wrapper is ready when you see large air bubbles when you remove the lid. Brush the top surface of the wrapper with a little canola oil, then tilt the pan over a piece of parchment paper so it faces downward, then scrape the wrapper off so it falls onto the parchment. Repeat until you've used up all the batters, and keep each wrappers sandwiched between parchments. Plastic-wrap the whole stack and set aside until needed.
5. PREPARE FILLING: Two hours before serving. Preheat the oven on 155 F/70 C. Rub the 1 tbsp of salt all over the salmon and let sit for 20 min, after which, rinse and pat dry with a clean towel. Place on a piece of parchment paper and rub the salmon with a bit of olive oil, then wrap tightly with the parchment. Place in the middle baking-rack (NO BAKING SHEET) and bake for 1:20 hour. Crumble the salmon into large pieces, and if you have a blow-torch, torch the surfaces so they're a bit charred. Gently toss the salmon with scallions and mayo (do the same if you're using lobster or lumpy crab meats). Set aside. Make the magic scrambled eggs. Set aside.
6. Lay one cheung-fun/rice wrapper with the oiled side down (that would be the top surface when it came out of the steamer, which is the pretty side). Scatter a few cilantro leaves across the middle, then a bit of salmon fillings and scrambled eggs. Gently roll it together, and repeat (only make as many as you're serving).
7. Place the rolls on a hot plate (the dish should be warm when served). In a small pot, bring soy sauce, light brown sugar and water to a simmer until the sugar has melted, then spoon the sauce over the rice rolls. Serve immediately.
