There are very many brands of egg tart crust, and the taste of different brands will be different. Personally, I think the taste of these brands are good:

Pretty Farmer: rich texture levels, layer by layer layering is obvious, will not be very greasy.

Kang Kang Le: relative to this brand's taste is more crispy, layers are not as much as Pretty Farmer's, but each layer is thicker, the flavor is also quite good, the bottom of the texture is relatively time-consuming good,

seven: and Kang Kang Le's texture is similar, but slightly greasier than Kang Kang Le.

Think: This has an okay texture and doesn't get soft or collapse when cold.

The tart crust in KFC is made of this brand of Si Nian, usually a pack of 18, about 16 dollars.
