Ait, I'll doubt the no prexisting opinions, but grant your point. Sometimes shitty people congregate.

But that doesnt mean all common quirks of the congregates are causal towards shittyness. 

Anyway I can see how you could miss how "do you miss the taste of meat?" is a little bit inflammatory, because out of context it isnt, but with the context of family in friends constantly asking such questions, many times with hidden motives, its a really tired one. But thats not your fault unless you meant it to be inflammatory.

You should never turn against any group or individual forever, that just impacts you negatively. 

Also I do not miss the taste of meat, I havent really ever, but meat was never my main interest as far as food was concerned. I'm a sauces and stews kinda guy.Powerful machine in a white and brushed-metal finish with an innovative dual-speed drive system so you can run the liquidiser and processor bowl from one base unit.
This versatile appliance has stainless steel slicing and shredding discs, a mixing/ chopping blade, a dough tool for pizza bases and pastry and fast pulse mode.
Gorgeous lipstick-red food processor comes with a commercial grade motor which can automatically adjust speed.
Chopping is extra-fast with the Sabatier blade included.
A heavy-duty machine with a high performance motor and plenty of attachments including a mini bowl and dual-feed tubes which reduce the need to cut food up for processing.
An extremely good-looking and super-shiny robust machine that has an extra-large food chute for easy processing, a meat chopper, a special slicing disc and reversible grating and shredding disc for your fruit and vegetables.
Attractive brushed-steel machine with three interconnecting bowls, nine tools for chopping, mixing and shredding and a special disc for emulsifying liquids. A dough blade, adjustable slicer and auto-pulse function are also useful features.Cottage cheese pancakes are an easy breakfast treat. These are much sweeter and arguably more delicious than your standard buttermilk pancake. However, these hardly use any sugar at all. While you can eat these with maple syrup, they go best served with sour cream and/or jelly (of just about any sort). I have been eating these since I was a child and must say they rank up there amongst my favorite foods. They are yummy.
Combine all of the ingredients together in a bowl until it basically looks like pancake batter.
Cook the pancakes over a medium flame.
When you start to see large bubbles start to form, flip them over to cook the other side.
Serve with sour cream and/or jelly.
looks great. can't wait to try!
These sound wonderful. I can't wait to try them. Finally, a healthier pancake!
The recipe seemed a little "wet" to me. I doubled the flour and it they worked out great! Delicious!
These. Are. Amazing. I just finished eating the first two, and I'm writing a comment to distract myself from the rest of the batch! XD They're so good with lemon curd on top too!
Large could work, too, if you don't mind the texture.
They are delicious! Great job!Nose- jams, so many dark and sweet berry jams. Like boiling down a mixed berry compote(blackcurrant, grape, raspberry, blueberry, blackberry, orange peels). Wine cellar in a vineyard, pickled and fresh ginger, raisins,!!Laddie lactic acid funk!! wet potting soil, ocean spray, minerality. I can smell wine! port, sherry, pinot noir, pinot grigio, merlot. Faint tropical fruits, pineapple and melon, lemon and orange zest, raw sourdough, milk chocolate, dark chocolate.

Palate- amazingly thick, dark fruits, berries, jams! Waxy, blackberries, figs, clementine, almonds, almond brittle, hazelnut liqueur, brazil nuts, leather and curing tobacco. Sherry, tart cherries and sweet cherry cocktail, wet rocks by the ocean, sweet dark grape jam, black liquorice, BIG dried plum, apricot and fig. dry and sweet, juicy and bitter.

Finish- medium long.!!Saskatoon Berries!! leathery dark fruits, nuttiness, bitterness and spices like cloves, pepper and allspice. Candied orange and ginger, minerality and Laddie funk, dried and curing tobacco, black liquorice and wines. Wines and oak  dryness are the last to go, I'm thinking a good Taylor Fladgate port from the seventies(thick, luscious, and sweet).

87/100- This is awesome, complex nose and palate but less so on the finish. the 2,3,4 are just a bit better to me though. I think they had a better balance with more bourbon barrel content in them. I have a few and am glad I do!!Ok yes they are a bit op 


STORYTIME!!!!: I wanted to "*HONK*" on Dr Doom and after I searched his house I couldn't find him so I go down to the vault and there's a aura just giving with the powers so since I was mad I couldn't "*Honk*" on him I attacked the aura and well the aura was big brained and attacked me from on top of he vault I ran on like 5 hp and hit a medkit then followed them through
