Preserving Onions…first try

So what do you do when you end up with six pounds of yellow sweet onions?  Yesterday when I picked up my Angel Food Ministries box we go another three pounds of onions.  I did a little research and decided to go with this:

SWEET ONION PRESERVES

1/2 cup Extra-virgin olive oil
3 lb yellow onion, peeled and thinly sliced
3/4 cup light brown sugar, packed
2/3 cup rice wine vinegar
1 c dry white wine
1 tsp Penzeys Spices Krakow Nights Polish Style Seasoning
1 tsp Freshly ground pepper

Warm oil in non-reactive pan over medium heat. Stir in
the onions and sugar. Reduce the heat to low, cover
and cook, stirring occassionally, for 30 minutes. Add
the vinegar and wine and cook over med-low heat,
uncovered, stirring occasionally, for 45 minutes, or
until mixture is thick. Stir in the tarragon and
pepper.

Prepare the jars, lids and boiling water bath. Fill
jars leave 1/4 inc headspace. Wipe rims with clean
towel and attach lids securely.

Place jars in boiling water bath, when water returns
to boil, process for 15 mins.

I have a feeling this will be yummy on hotdogs, hamburgers, hamburger steak, even steamed veggies! I know it smells good and has a sweet tangy taste too!
