Wash and finely chop 4 cups of methi leaves. Keep them aside.
In a mixer jar, add 3 green chilies, 1-inch ginger, 6-7 garlic cloves, and 1 tsp cumin seeds. Crush them into a coarse paste. Keep it aside.
In a mixing bowl, add 3 tbsp curd, salt to taste, ½ tsp turmeric powder, 1 tbsp red chili powder, 1 tbsp coriander powder, a pinch of hing, ½ tsp ajwain, 1 tsp garam masala, 2 tbsp sesame seeds, 1 tsp fennel seeds, 2 tbsp sugar, 1 tsp lemon juice, and 2 tbsp oil. Mix well.
Add the chopped methi leaves and the ground chili-ginger-garlic paste. Mix well.
Add 1 cup besan, ½ cup wheat flour, and ½ cup rava. Mix well.
Add a little buttermilk and knead into a tight dough for muthiya. Do not knead a soft dough.
Grease your palms with oil and take about 2 teaspoons of the dough, shaping it into small oval-shaped dumplings. Do not make large muthiyas. Shape all muthiyas the same way.
Heat oil and deep fry the muthiyas on a low-medium flame until they are slightly crisp and golden brown on both sides.
Let the fried muthiyas cool down and store them in an airtight container. They stay good for 8-10 days.
Serve crispy methi muthiyas with hot tea or coffee.
