The nesting time of Laotan's whole grain nest materials varies depending on the production method, weather and other factors. Generally speaking, it takes **30 minutes** to **1 hour**.

The following is a list of ingredients and preparation steps for Laotan's multi-grain nest materials:

Ingredients list:

* Corn grits: 1000 grams

Preparation steps:

1. First, put broad beans and soybeans into a pot, add appropriate amount of water and cook until cooked.

2. Take out the cooked broad beans and soybeans, wait for them to cool and send them to the grain processing point for crushing (coarse crushing is required, and more than half of the crushed materials are small particles).

3. Add wheat bran and millet to the crushed broad beans and soybeans, and mix evenly.

4. Use a small rural machine to press oil from the rapeseed cake, then add the fried bran to the mixture and mix evenly.

5. Add koji wine to the mixture and stir evenly.

6. Add appropriate amount of cooking oil to the mixture and stir evenly.

7. Finally, put the mixture into a container, seal it, and leave it for 24 hours before use.

The prepared Laotan grain nest material can be put into a plastic bag, tied tightly, and stored in a cool place. It can be stored for up to half a year. When using it, you can add an appropriate amount of water to dilute it as needed, and then pour it into the fishing point to make a nest.
