Need Indian Lemon/Lime Pickle recipes

So I want to broaden my cooking skills a bit and get into pickling. Since I like lime or chili pickles from Indian brands and due to inflation they become expensive (like 3.5€ / glass) they sound like a good option to start.

Beside the lemons I plan to use mustard seeds, fenugreek, chili powder, tumeric and asafoetida (in German it's called Teufelsdreck, lit. "devil's dirt"), cause those were the ingredients of the last pickle I ate. I obviously googled some recipes and found the following two which sound promising:

a) Elumichampazham Urugai

b) https://paattiskitchen.com/homemade-indian-lime-pickle-recipe/

But maybe some of you has some tips or maybe even a family recipe from your mother/grandmother? !bharatiya help a mayo out!
