Why do fried fritters have to be fried together?

When deep-fried dough sticks are fried, the two pieces are fried together, on the one hand, for uniform heating and good taste, and on the other hand, for good looks.

When the fried dough sticks are put into the pot, they will expand rapidly under the influence of high temperature, and the stuck parts will remain unchanged because they are not affected by high temperature, making the whole fried dough sticks look very fluffy and crisp and full of taste.
