Why is the sandwich wrapped so tightly?

1. Square toast sandwich: Take a piece of baking oil paper, the width of which is about 2~2.5 times the length of toast. Near the middle of the sandwich, fold it in half. First, fold one side into a triangle, fix the position, fold the other side, and put the tip of the triangle into the crease.

2. French stick sandwich: Take a piece of baked oil paper, the width of which is about 65438+ 0.5~2 times the length of French stick. Lift a corner, roll it up close to the sandwich, fold the left and right sides in half to the middle, and continue to roll the sandwich forward. The last corner will be collected in the crease.

3. Pocket sandwich: Take a piece of baking oil paper, the width of which is about 2.5~3 times the length of the sandwich. Fold the opposite sides inward about 2cm, put the sandwich in the middle of one side, fold the other side up to wrap the sandwich, and fold the left and right sides to the middle. If it needs fixing, it can be fixed with tape paper or hemp rope.
