Here are the ingredients you will need for making hoppers; rice flour, semolina, sugar, salt, milk, water, and yeast. (water is not in the photo)
Place the rice flour, semolina, 1 teaspoon of the sugar, salt, and yeast in a large bowl and mix well.
Add water a little at a time and mix well until you have a smooth batter without any lumps.
Cover and leave to rise for about 6 to 8 hours in a warm place (if cold environment).
After good fermentation, the batter will be frothy, bubbly, and smell fermented.
Add the coconut milk a little at a time to make the batter thin and then gently stir until you have a smooth batter without any lumps. Add the rest of the sugar and mix.
Dissolve the baking soda in a tablespoon of water. Add to the batter and mix well. Don’t forget to add salt to taste if needed. Rest the batter for about 30 minutes in a warm place.
You will see a lot of tiny bubbles in the batter after resting time. The bubbly and creamy texture is the key to the best hopper batter. You can use the batter immediately to make hoppers or keep it in the fridge for later use.
Heat the pan over medium-high until it becomes hot. Pour a ladleful of the batter into the center of the pan. You will know the temperature is right when the batter makes the sizzle as it goes in.
Hold both handles of the pan then rotate the pan to spread the batter evenly and thinly. Swirl once (or twice) in a circular motion in the same direction to the top edge of the pan. You will know the temperature of the pan and the consistency of the batter are correct when you swirl it, it sticks a nice layer around the edge of the pan.
The hopper batter around the edge should be thin and dotted with little lazy holes, and there should be a thicker layer in the center.
Cover and cook for about 2 minutes over medium heat until the edges of the pancake are starting to brown and the center is no longer runny. Adjust the heat as needed.
Remove the lid. If you want a crisp edge, turn up the heat and cook for a few seconds more. The center of the hopper should be puffed and soft.
Run around the edges with a palette knife or spatula and ease onto a plate.
