Given the background description of some cooking related query, summarize the question into a title

Ex Input:
I am relatively new to deep-frying. Having seen the questions about oil reuse and conservation, I'm still at a loss about what's going on with my oil...My sunflower oil foams like crazy. I've been reusing this oil for a while now and was going to discard it, however a friend of mine told me this oil was still looking good. Relatively clean (I filter it regularly), no off smell and it doesn't smoke (in my fryer, that is). I only fry potatoes in this batch of oil to avoid flavor transfer. These are cut into French fries, chips or straw potatoes. Specially the chips and straws retain a lot of water, and I guess that has something to do with it.Also, I noticed the frying takes longer with the foaming oil.Edit: I've tried poaching(?) the French fries, but they foam during poaching. Then when frying, they really foam. I have to keep an eye on it or the oil spills over the top. Anything I can do about it, or should I just go ahead and discard the oil altogether?Edit: Serious Eats has an article about frying oil.

Ex Output:
Frying - Oil foams

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?

Ex Output:
Can bright green avocados be ripe?


Ex Input:
I really enjoy cooking eggs for breakfast, and sometimes I'm feeling fancy enough to add veggies into my scramble. However, I'm never sure how to prepare the veggies to put into the scramble. If I don't cook them, usually they are too crunchy or tough (and sometimes make the scramble watery), and don't taste good with the eggs. If I try to cook them before adding them, they usually come out too dry/overdone. I figure this might depend on which veggies I'm cooking so here are my common favorites: tomatoes, bell peppers, mushrooms, onions (suggestions welcome!)To make my question more specific (and hopefully more answerable): how can I prepare the veggies so that they are not crunchy, but not over-cooked?

Ex Output:

Proper preparation of veggies for an egg scramble
