Onions

There are so many onions available these days. Bottomline, they do add sweetness to your dish, soup, stew etc. but the degree of sweetness varies according to the colour. This is my deduction, in ascending order of sweetness:

1. shallots
2. Small purple onions (resemble shallots but are slightly bigger)
3. Red onions (great for relishes, salads, grilling)
4. Yellow onions (great for soups and omelette)
5. White onions (great for grilling, onion soup)

Pearl onions are smaller versions of white onions but in terms of sweetness, are somewhere between 3 and 4. Great for pickling too.
