Procurement of turtles
Although cauliflower turtles are in season, the quality of the high-growth greenhouse turtles and the ecological turtles stocked in the outer ponds are sold.
Therefore, chef friends should give priority to the purchase of ecological turtles. How to distinguish between ecological turtles and greenhouse turtles?
The first thing to look at is the back shell. The back shell of the ecologically farmed turtle (commonly known as the outer pond turtle) is bluish green, the abdomen is white, and the oil is yellow. However, some dorsal shells are gray-black with five dark black patterns (commonly known as five golden flowers); the abdomen is gray, and there are also five dark black patterns.
Also look at the toes. The toes of wild turtles and ecologically farmed turtles are sharper, and the toes are thin and pointed; while the turtle greenhouse pond is surrounded by cement walls, and the claws of the turtles are blunted due to long crawling, so the toes of the greenhouse turtles are not as thin and pointed as the ecological turtles.
<h1>So, what's the secret to chef friends buying turtles? </h1>
1. Visual inspection
First of all, look at its shape and movements, if the appearance is complete and harmless, the muscles are thick, the skirt is thick and upturned, the ribs of the dorsal nail are blurred, the abdominal nail is shiny, and the movement is agile, that is, it is an excellent turtle.
2. Grasp by hand
Then pinch the armpit of the hind legs of the turtle with your hand, such as the turtle pedaling on all fours, the activity is rapid and fierce, that is, the superior turtle; if the four legs are slightly moving, the movement is not flexible, it is an inferior turtle.
3. Turn over
After that, the turtle is flipped upside down and placed on the ground, if it can turn over quickly with its head and legs, and can quickly escape, it is a superior turtle; if the turtle head and leg are not well coordinated, the flip is slow or very difficult, and the action is slow when escaping, it is an inferior turtle.
4. Neck check
Finally, use bamboo chopsticks to stimulate the turtle, let it bite the bamboo chopsticks, and then stretch the neck, touch its neck with your hands, if it is a hook fishing turtle, it has a needle-like hard object. This type of turtle should not be stored and transported for a long time, let alone suitable for cooking.
