Portuguese egg tarts don’t feel any different from ordinary egg tarts. Maybe everyone has different tastes, so they may taste different, but generally they are sweet and milky. The aroma, the authentic Portuguese egg tart liquid generally has this flavor, so you can buy it and taste it yourself, you may feel it differently from others.

As for the taste of Portuguese egg tart liquid, I personally feel that it is no different from ordinary egg tarts. Some stores will add milk when making the egg tart liquid, so it will taste more milky. Some will put blueberry jam and coconut fruit on the egg tart, and some will put strawberry jam, so it will taste different. It's different, but generally it has a very ordinary egg tart flavor.
