Sift the flour into a bowl and add the salt, oil and water.
Whisk together. You can use a blender.
Strain this batter through a strainer.
Add a little water to a saucepan or a high-edged pan of the same width as the skillet for the double boiler.
Once the water is simmering, place the skillet on top.
As soon as the skillet is hot, dip a brush or a small sponge into the batter and, using a circular motion, coat the entire surface of the pan with a thin, film-like layer.
Pass the brush coated with batter again over the areas that are not well covered. Be quick, as the sheet dries quickly. See the picture and video tutorial above.
The sheet is ready when the top is dry, and the edges begin to peel away. It doesn’t need to cook for long, as it sets almost instantly when brushed. The edges of the sheets must not be allowed to dry out.
Carefully remove the sheet with your fingertips and place it on an oiled plate. Lightly brush it with a little oil to prevent it from drying out and sticking to the next sheet.
Cover the plate completely with plastic wrap to keep the sheets soft and prevent them from drying out in the open air.
Continue baking the spring roll wrappers in the same way as above. Stack the sheets on top of each other, making sure to lightly oil each one and cover it with plastic wrap each time.
Use the brick sheets the same day, preferably within 24 hours, to keep them very flexible. Make sure to wrap them tightly in plastic wrap.
A little tip:You can directly create strips as you brush the batter. These strips will be used to make cigars without having to cut the discs of sheets.
