Shrimp tempura is a well loved dish worldwide. Juicy shrimps coated in a light and crispy batter, what's not to like? In Japanese, the word for shrimp is ebi (海老) so we call the dish "ebi no tempura" or "ebi ten" (海老天) for short!
Ebi ten can be served on its own, but it's also common to serve it on or with other dishes such as udon soup (kake udon), tempura soba, tendon (tempura rice bowl) or even in onigiri rice balls (tenmusu)!
If you can master shrimp tempura, it opens up a whole world of other Japanese dishes you can incorporate it into!
WHAT IS TEMPURA?
Tempura is a classic Japanese dish with a long history. It's typically made with seafood and vegetables that are coated in a simple batter made from flour, egg and water. It's then deep fried for a short time, tempura should be light in colour and texture.
PREPPING PRAWNS
Prepping prawns can be very annoying but proper preparation leads to successful tempura shrimp. So here are my tips for preparing the prawns!
DEFROST THOROUGHLY IF YOU USE FROZEN SHRIMPS
If you are using frozen prawns, defrost them completely under running water. Non-frozen prawns can be simply chilled in the fridge.
REMOVE SHELLS AND DEVEIN
Remove the shells by splitting the shell in the middle of the legs and pulling it clean off.
For deveining, cut down the back of the shrimp to reveal the vein. You can pull it out using the tip of the knife, a toothpick or your fingers.
If you don't want to cut it, you can use a toothpick to pull it out from the top. (Although sometimes it snaps if you do this so be gentle.)
WASHING SHRIMPS
Only two things are needed to wash shrimps properly
Starch
Salt
Salt dehydrates the shrimp which improves the texture and starch absorbs the dirt.
Place the shrimp in a bowl with 1 tsp of corn starch and a few pinches of salt. Rub it all over the surface of the shrimp until completely covered and then rinse with water. This makes them super clean and they always taste better if you do this!
CUT THE TAILS
There are 3 tails on a shrimp, two fins on the sides and a pointy one in the middle.
Place the shrimp on its side and with the tail folded in half and trim it diagonally. This prevents oil from splattering out when it’s frying.
MAKE INCISIONS
To keep the prawns straight, it's important to break off the muscle!
Place the prawns on a chopping board with the tail to the right and make incisions into the belly. We make 4 incisions across the whole body and it should be about ½ way through the prawn. Then you gently press the back of the shrimp to stretch the muscle.
This process prevents prawns from curling when they're frying.
DRY AND PUT THEM IN FRIDGE
Once you've followed the tips above, rinse them in cold water and pat them dry with kitchen paper. Put them in the fridge until just before battering.
Keeping the ingredients cold is key for tempura in general as well.
TIPS FOR MAKING TEMPURA BATTER
Making tempura batter from scratch is simple to make yet difficult to perfect. Here are a few tips that I think are vital to making successful tempura batter:
Sift the flour
Use ice cold water
Mix starch with the flour (Potato starch or corn starch)
Use sparkling water (or lager beer even)
Do not over mix (Leaving lumps is actually better than smooth batter)
USING MAYONNAISE
Don't get me wrong, I still prefer using egg to make tempura batter. However, using mayonnaise is a great alternative when you want to make small batch. (Measuring ½ or ¼ of an egg is such a pain, but you can do this if you prefer.)
The general usage ratio of mayonnaise is, 1 egg = 1 tbsp mayonnaise.
It is not gonna have any mayonnaise-like flavour but please note that this only works with mayonnaise contains egg. I always use Kewpie mayonnaise.
TIPS AND TRICKS TO MAKE AMAZING SHRIMP TEMPURA AT HOME
To make good shrimp tempura at home, it is not only important to know tips to make tempura in general but also processes to make shrimp tempura specifically.
So here are my tips and tricks for making shrimp tempura!
FLOURING BEFORE BATTERING
One of the saddest mistakes in tempura is when the batter comes off.
To avoid this, dry the shrimp with a paper towel and then dust them with flour before battering. That way, the flour will act as an adhesive between the shrimp and the batter.
IDEAL TIME TO COOK
The general frying time for prawn tempura is around 2 minutes at an oil temperature of 180-190°C (approx 355-375°F). The key is to fry it quickly at a high temperature.
However, there are roughly 3 points to look at to know when you should take the shrimps out of oil.
Colour: the surface of the batter should be a lightly golden, not dark.
Sound: the batter will make a loud crackling sound when it is first placed in the oil, but towards the end, the sound will become "high-pitched" and the foam will become smaller.
Float: When the prawn is ready to be removed from the oil, they rise to the surface and float.
DON'T OVERCROWD THE POT
If you put too many shrimps in a pan at the same time, the oil temperature will become too low and the tempura will not be crispy.
The key to crispy tempura is to keep the temperature of the oil high so make sure to only fry a few shrimp at a time. If you fry tempura in small batches, you are more likely to have successful tempura. (This also stops them sticking together.)
RECIPE
How to make a small batch of light and crispy shrimp tempura (ebi ten). Makes 10.
INGREDIENTS
10 large shrimp (Japanese tiger, black tiger or white legged)
100ml cold water
50ml sparkling water
15g potato starch or corn starch
75g weak flour (cake flour or all purpose) + extra for dusting
½ tbsp mayonnaise (or half a small whisked egg)
2 ice cubes (optional)
Oil for frying (vegetable, canola, peanut or white sesame)
Cook Mode Prevent your screen from going dark
INSTRUCTIONS
Measure out 100ml of water into a jug and place it in the fridge for 20-30 minutes. Place sparkling water in the fridge too. (Preferably an unopened bottle.)
Sift 15g potato starch and 75g cake flour into a bowl. Mix them together and place the bowl in the fridge for 20-30 minutes.
While your tempura batter ingredients are chilling, prepare your shrimp. Remove the shells and veins (see in post for how) but leave the tails intact.
Place the prawns in a bowl with 2 pinches of salt and 1 tsp of corn starch and rub them over the surface of the prawns.
Once evenly covered, wash the shrimp under cold running water to rinse off the salt and corn starch.
Dry them with kitchen paper and transfer to a chopping board.
Place the shrimp on its side and with the tail folded in half and trim it diagonally. The pointy tip should be cut off and be the shorter part of the diagonal. (This stops oil from splattering out when it's frying and it looks nicer too!)
Turn the prawn so the belly is facing up, and make diagonal incisions along the whole body. The incisions should be about 1cm apart and go about ½ way through the prawn.
Once 30 minutes have passed, start preheating your oil to 180-190°C (355-375°F).
In a bowl (or jug), add a few tbsp of the chilled water and ½ tbsp of mayonnaise. Mix until well combined, this loosens up the mayo. (Alternatively, whisk a small egg in a separate bowl and add half to the water instead.)
Pour the rest of the chilled water and 50ml of chilled sparkling water into the bowl.
Add the flour/starch one third at a time, gently drawing crosses through the mixture with the chopsticks to incorporate it. (Do not whisk or over mix.)
Test your oil by adding a drop of batter, if it sizzles and floats you're ready to fry.
Add a couple of ice cubes to the batter and mix to make it extra cold. (optional)
Dry the shrimps with a paper towel and coat them thin layer of flour.
Dip them in the batter and then carefully place them into the oil. Make sure not to overfill the pot. (Keep the batter in the fridge between batches.)
Fry for about 2 minutes or until crispy but before they turn golden.
Once cooked, place on a wire rack to allow the excess oil to drip off.
Serve and enjoy!
NOTES
This recipe makes a small batch and uses mayonnaise instead of eggs. If you want to use egg, whisk the egg in a separate bowl and use half.
