So many to choose from...
1) I didn't have lemon juice so I used kumquat juice. Quantity: 3 tbsps
2) I used approx 75 g of sugar
3) I used all-purpose flour, Philadelphia Cream Cheese (250 g) and Paul's thickened cream (250 mL)
4) I greased the surface of the rice cooker with vegetable oil in lieu of butter.
The result? Slightly tangy, mildly sweet and deliciously cheesy!
I am very encouraged by the result and I am looking forward to making a better version next time! :)
