Peel and devein the shrimps, leaving the tails intact.
Cut 4 incisions in the under-section of each shrimp and straighten
them out.
Coat the shrimps lightly with flour, leaving the tail uncoated, and
shake off the excess.
In a bowl, gently mix the tempura flour, water and egg yolks and use
at once (the batter will b e lumpy, don't over mix).
Heat the oil in a deep pan or wok to moderately hot.
Working with a few at a time, dip each shrimp into the batter, still
leaving the tail uncoated.
Fry briefly in the hot oil until lightly golden; remove from the pan
and drain well o n paper towels.
Repeat this process with the vegetable pieces, doing about 2 to 3
pieces at a time.
Serve immediately with soy sauce.
Add strips of fresh ginger to the soy sauce if you like.
Note : Tempura flour is available from specialty Asian shops, and makes
the lightest tempura batter. Plain flour can be used but the batter will
be slightly heavier.
