Place the corn kernels in a mixing bowl, ensuring they are all separated.
In a separate mixing bowl, incorporate the flours, salt, MSG, baking powder, spring onion, kaffir lime leaves, chilli paste and sesame seeds.
Slowly add the tonic water and mix gently. The mix should have the consistency of a thick batter.
Add most of this mixture to the corn and incorporate well using a light touch.
In a tall-sided saucepan, heat around 4 cm of neutral oil to 180°C.
Place an oven tray with a wire rack covered in kitchen towels next to the saucepan.
Place the fritter mix on a kitchen scale and turn the scale on. Using a large spoon, scoop a spoonful onto a soup serving spoon and shape so that no corn will fall off the mix. Check the scale, as a guide you should have used around 100-120 g of the mixture to form the fritter.
Hold the serving spoon over the saucepan almost touching the oil and using the large spoon, carefully scoop the batter off the serving spoon and into the oil.
Start a timer and turn the fritter after 1 min 30 secs, or after the fritter appears safe to turn over without breaking, using a small slotted spoon or a fish slice. After another 1 min 30 secs, the fritter should be golden brown.
Remove from the oil using a slotted spoon and place on the oven tray. Repeat until all the mix is used up. If you're making several burgers keep the cooked ones in a warm oven.
