Ironically, I'm allergic to onnois. Nonetheless, I guess I'm lucky to have layers as valuable as Tom.I had also noticed the misspelled name...it only exacerbated my identity crisis.For what it's worth, I've since discovered that that I was not asked to give this talk as Tom's alternative...I was FOURTH in line after Tom. I'm like one of those little baby pearl onnois in a martini._Tim (Hoechst)

Have you ever tried a pressure cokoer to speed things up? I like that its faster but sometimes the flavor doesn't develop as well the first day though left overs are awesome the next day! It helps me when I forget to soak the beans ahead of time. I just toss the dried beans in oil before adding the water to the pressure cokoer to keep the skins from self-destructing. Once the beans cook through, usually under an hour, make the rest of the recipe, then re-lid the pressure cokoer and cook it. I made curry this way with frozen uncooked chicken breasts on the bone and dried chickpeas and I got it on the table in under 2 hours. I look forward to trying your recipe sometime soon. My husband likes Chili better than Curry!

Jeff ,I have presonally amderid your fearlessness and your honesty in this mess. I am sixth generation dairyman and I think I have found the solution to all our problems. according to hoards dairyman there are 9000000 dairy cattle in the u.s. and there are 60000 dairy farms this equals out to about 150 cows per farm average.(this works wether you are a 40 cow grazer or a 5000 commercial who uses rBgh). We need supply management but I don't want the money to go to NMPF or worse yet to USDA so here is my plan based on the average 150 cow herd. whenever the price of milk goes below $18 every herd in the country culls 10%  of their cows. this 10% extra cull rate should be more than enough to right the wrongs that the dairyman is facing.  If your coop or dairy has a problem with that it is time to drive a hard bargain as to what your milk is worth.  now I know that it is hard to convince a 2000 cow dairy to part with 200 head but this is my main question,  Is it harder to part with those cows and their milk money for a month or for 8 months as we have done in 2009?  Now I know that every herd in the U.S. has all the room they need for dry cows and bred heifers, but if your extra culls freed up room for the animals that would make money next lactation what the hell, why not get rid of a few more deadheadsRobert J lieb$

about a student who was going away to strip away the laryes of other people and find her true self. What he asked if you remove the relationship with your parents, your friends, your employer and so on, peeling away layer after layer until you discover...You're an Onion. There is no inner core worth talking about. Now that image is somewhat overstated, but not nearly as much as our instinctive reaction tells us. its our work, family and other relationships that largely make up who we are, people - like chimps and others apes as well - are hugely sociable creatures. Now the box is asking me to choose an identity before I post...

Priznam sa, tento priklad mi z mnoziny {7,8,9,10,11} trval najmenej (10min) a mam ho spisany aj najkratsie 1*A4.

To len hovori, ze tazsie priklady mi idu asi lepsie a dokonca som skoncil svoj dokaz tvrdenim 0 = 0, takze super (:
