culinary experiment: Welsh rarebit
All of those recipes called for a double boiler. I was speculating about combinations of pans we have that might be pressed into service; a double boiler is just a pot full of boiling water holding a smaller pot with your food, after all. I speculated that this style of indirect heat was to keep the cheese from burning. Dani pointed out that the problem with cooking directly over low heat (you'd need low heat to prevent burning) is that the heat is concentrated in the center of the pan -- but we have a pan that's very good at distributing heat, so maybe I could cook directly in that. That seemed like a good idea.
That was the only deviation I made from the recipe. Other than that I followed it meticulously -- more meticulously than I normally would for regular cooking (as opposed to baking), actually. I even measured the spices.
In high-level form, the recipe is: melt butter, mix in flour, stir until it thickens; add spices (dry mustard, cayenne, paprika) and Worchestershire sauce and stir until blended; add beer and stir constantly until thickened; add cheese and stir occasionally until melted; lightly beat eggs and mix in (first adding some of the cheese to the eggs, I assume to prevent quick-scrambling the eggs).
After the cheese had been cooking for a while it was fairly smooth but not exactly liquid; when I scoped out a spoonful, for instance, it formed a lump rather than pourable sauce. After several minutes of it not changing state further, I proceeded with the egg step. It was hard to get a smooth mixture with the eggs and the small bit of sauce; when I then poured all that back into the pan it was even harder to blend. I wasn't sure whether to leave the pan on the heat while trying to blend it, but I did. Eventually I ended up with something that was mostly blended, except there was some clearish liquid separating out. (Butter? Some chemical subset of the cheese? Not egg.)
It tasted pretty good over toasted French bread, but the consistency was a little too far toward the lumpy side. I'm left wondering whether the double boiler plays a role beyond heat distribution or if I did something else wrong. Maybe some day I'll try it with the double boiler and see what happens.

Chances are, the mixture was, if not burned, thoroughly over-heated because of the direct heat.
You can fake a double boiler by using a metal bowl over a saucepan full of water, or even a bigger saucepan over a smaller.
(I bet the clear liquid was some form of whey.)

Ah, good point. I had assumed that the very lowest setting on the burner would not be too hot (and that it would just take a long time for the cheese to melt, which it did), but you might be right that it was over-heated.
I was going to fake it with two saucepans, though I don't quite have the right combination of sizes for the amount I needed to cook. I hadn't considered a bowl; good idea.
(I bet the clear liquid was some form of whey.)
That seems plausible. The only time I've seen whey (and known what it was) was from a soft cheese (cottage, I think); I don't know how it differs for hard cheeses (cheddar, in this case).

Of course, you meant 100 degrees Celsius, or 212 degrees Fahrenheit. Or 373.16 degrees. (Technically, "degrees" with no qualifier is Kelvin, but from context you meant Celsius.)
Also note that that's the boiling temperature at standard pressure for reasonably pure water; adding salt raises the boiling temperature, while high-altitude (i.e. lower pressure) lowers it.

Unless, of course, it's in the solid stat...
Oh, wait. I'm doing it again. So sorry :-)

Yes, the wrongness of the temperature of direct heat is what caused the rarebit to go wrong. The extra bit of liquid and the lumpiness are caused by the direct heat. Cheese doesn't turn into those lovely sauces very well, with all their odd bits intact, unless they get the super-slow melt of the correct type of heating implement. I ruined a very expensive bottle of wine (at least expensive by the standards of being used to cook) and a block of gruyere (sacrilege to ruin gruyere!) by trying to do a fondue on the stove when my first fondue pot had unexpectedly bitten the dust (one half hour before a dinner party). The result was much like you described: Mostly saucy in texture, but lumpy and with a disturbing amount of extra liquid. As all my previous fondues would have made Julia Child proud, it was obvious that it was the faulty cooking method to blame.

I wonder (but haven't done the research) whether "rarebit" is actually the newer word. I can't explain why, but it feels like a back-construction. So my hypothesis is: "rabbit" is a corruption of something (that has been lost); "rarebit" is an attempt to rationalize "rabbit".

Re: lumps. There are some foods that sieze when a magic ratio of binder to liquid is reached. Often, adding more liquid (or removing excess and re-mixing if it separates) will fix the problem. This happens with roux, chocolate, mayo, and a few other emulsions. I wonder if a similar recovery trick might have worked: pull off the liquid, re-mix the solid part, and then slowly re-integrate the liquid. Just a guess.

Re: the lumps, mixing with a stick blender would help get rid of them, too.

Basically, you stick it into whatever you want to blend. It works great on the stove (the blades are recessed so they won't nick your cookware).

The upshot is that it doesn't affect the taste as much as the texture so at least you were able to discover that you really like the taste enough to invest in a double boiler!
Rabbit/Rarebit
It's supposed to be 'rabbit." "Rarebit" is folk etymology.
I can ramble on this more if you wish, but it gets vaguely anti-Welsh in its origin.
Re: Rabbit/Rarebit
Thanks. I'm curious about the origin of the terms.

Tonight, I'll type up a summary of what they say.
