Heat milk switch off the gas and add vinegar mixed with water. Strain the curdled milk in a cloth. Wash it with water.

Remove the excess water from it. Grease a spring mould. Place a butter paper on it. Also Grease the butter paper. Grind all the biscuits to a fine powder.

Heat the butter, add it to biscuit powder and mix it well.

Make a layer of this mixture in the mould by pressing it firmly and evenly. Put it in a fridge to set for 15 mins.

Now in a bowl take curdled milk, hungcurd, fresh cream, sugar cornflour, vanilla essence and beat it nicely. You can also use mixer grinder.

Pour this mixture on the set biscuit layer. Tap a little to release air bubbles. Place it in a pre - heated steamer, steam for 30 mins.

Let it cool for an hour or two.

After it cools completely spread the strawberry marmalade and let it set in a fridge for two hours. Here I have used homemade marmalade. Recipe's link https://cookpad.wasmer.app/in/r/17097465
