Making the batter: mix together flour, salt, turmeric, egg, beer and corn starch in a medium bowl. Set aside and let the batter sit for at least 30 minutes.
In a large pot, heat enough oil to deep fry fritters (recommend to fill the pot half way with oil)
When oil is ready, put half hand full of sweet potato into batter then carefully transfer the mixture to oil pot. Try to spread out sweet potato mixture into a nice round base for your fritter.

Use a sieve to pick up flour batter formed in the oil
Wait about 1 to 2 minutes or until the sweet potato base are bound together, then carefully put one shrimp on top.
When the base start to turn golden brown, use a spoon to turn the whole fritter upside down and fry for another 3-5 minutes
Then transfer the whole fritter to a pan lined with paper towel to absorb excess oil and cool down.After 5 minutes, serve immediately with your favorite dipping sauce. You can also garnish them with cilantro before serving.
