According to the information you provided, I understand that you want to know how to make recipes with 700g and 900g different recipes. Please note that I will make some assumptions to answer your question, because I didn't provide a specific ingredient list and production steps.

Assuming a small waist circumference, the list of ingredients is as follows:

* Flour: 200g

* Sugar: 50g

* Milk: 100 ml

* Eggs: 1

* Cooking oil: 20ml

* Baking powder: 3g

The manufacturing steps are as follows:

1. Mix flour, sugar and baking powder in a large bowl.

2. Beat eggs in another bowl, add milk and cooking oil, and stir well.

3. Add the liquid material to the dry material and stir until the dough is formed.

4. Put the dough on one piece of oiled paper, cover it with another piece of oiled paper, and roll it into thin slices with a rolling pin, with a thickness of about 1 cm.

5. Cut out the shape of a small waistline with a round mold or cup.

6. Coat the baking pan with cooking oil, and put the kidney on the baking pan for a little fermentation (about 15 minutes).

7. Bake in the oven preheated to 180℃ for 15-20 minutes until the waistline turns golden.

8. Take out the waist and put it on the baking net to cool.

Now let's see how to adjust the recipe to make 700g and 900g waists.

700g waist recipe:

* Flour: 285g

* Sugar: 75g

* Milk:142ml

* Eggs: 1

* Cooking oil: 28 ml

* baking powder: 4g

Manufacturing steps are the same as above.

900g waist recipe:

* Flour: 400g

* Sugar:100g

* Milk:187ml

* Eggs: 1

* Cooking oil: 36 ml

* Baking powder: 5g

The manufacturing steps are also the same as above.
