PROBLEM: I very rarely buy avocado, but now I happen to have two of them in my kitchen. I'm used to ripe avocado having this colour:Now, mine are more brightly green, like this:They aren't very soft, so I guess they aren't ripe yet, but I'm wondering if the colour will change or if this is just a matter of which variety of avocado it is?

SOLUTION: Can bright green avocados be ripe?

PROBLEM: I recently made custard with a huge amount of milk, custard powder and sugar. After boiling it for few minutes I added vanilla essence to it. After it was settled I added apple and pineapple. Then I placed the whole mixture in the fridge and the custard was tasting fine at that time. But after a half hour of cooling, when I tasted the mixture it was bitter. I googled about the issue and found out that milk and pineapple are not good friends, but I don't want to waste the whole thing now. Is there any way to reduce the bitterness?

SOLUTION: How can I remove bitterness from custard after adding pineapple to it?

PROBLEM: I bought some printed rice paper decorations (flat circles of rice paper printed with edible ink) for my son's birthday party. I'm not sure what the best way is to attach them to cakes / cookies and I don't have a lot of spare time to experiement.The options I can think of are:make my own cookies and press them in to the cookie - either beforebaking or more likely after baking but while still warm and softplace the rice paper circle on top of a pre-baked cookie or small flat-topped cake and pipe some form of icing or frosting around theedge to hold it in placepile butter cream icing on top of a small cake, press the rice paper circle onto the butter cream icingWhat I ideally want is to be able to do this the day before they are needed, so as well as being held properly in place, I also would like the rice paper not to go soggy / curl up and the ink not to run or leak out of the rice paper.

SOLUTION:
