Peel and roughly chop 200 grams of dudhi (bottle gourd).
In a mixer jar, add 1 cup of the dudhi pieces, 2-3 green chilies, 4 garlic cloves, ¼ cup coriander leaves, ½ tsp lemon juice, and a pinch of salt. Grind into a smooth paste without adding water.
Transfer the ground paste into a mixing bowl. Add ½ tsp turmeric powder, ½ tsp red chili powder, ½ tsp coriander powder, ½ tsp ajwain (carom seeds), a pinch of hing (asafoetida), 1 tbsp white sesame seeds, ½ tsp dry mango powder, and 1 tbsp kasuri methi (dried fenugreek leaves). Mix well.
Add 2 cups of wheat flour, salt to taste, and 2 tbsp oil. Mix well and knead into a medium-soft dough. The dough should bind with the water content from the dudhi paste, but if needed, add 1-2 tbsp of water while kneading.
Pinch off a medium-sized ball of dough, roll it into a ball, and flatten it.
On a rolling board, roll the ball into a thin thepla.
Place the rolled thepla on a hot tawa and cook for a minute.
When the base is partly cooked, apply some oil or ghee and roast the thepla on medium flame. Repeat for all theplas.
Serve the dudhi thepla with dahi tikhari.
