Take Full fat yogurt in a serving bowl and whisk well. Peel and chop cucumbers into small cubes.
Add the chopped cucumbers to the whisked yogurt and mix well.
Take fresh and tender ajwain leaves. Heat a tava, add a tsp of oil, add the ajwain leaves and saute until they wilt. this is will take 5-8 minutes. Once the leaves wilted, add cumin seeds and saute for a 30 seconds.
Take the wilted ajwain leaves and cumin seeds in a mortar-pestle and grind it to a paste. I prefer mortar-pestle, you can also mixie.
Remove the ground paste of ajwain leaves and add it to the cucumber yogurt, add salt and mix well.
Finally garnish it with red chili flakes and serve it along one-pot meals.
