Balsamic comes in various ages. Couple of years to 25 and some even older. Get an old one 15 to 25 years old to put on ice cream and strawberries and old cheeses. Get a 6 or 8 year old to have on salads and broschetta and dipping bread.
Good nuts are expensive. If you can find pine nuts and hazel nuts at 20% off anywhere, buy them.
I don’t know if the store in question carries Rustichella D’Abruzzo. If they do (WholeFoods does), get that.
Good pasta doesn’t have to be expensive. WF brand is excellent and is very inexpensive actually. But if you can get the Rustichella D’Abruzzo on sale, why not treat yourself?
Oh, another thing I’d look for is dried mushrooms. They last forever stored in a cool dry place and reconstituting them in some warm water and cooking with them is really wonderful.
