Yeah, HP is a bit marginal - that´s why I treat it the same way I use to handle Tobasco Sauce (the original one) - it isn´t that sour and aromatic in the beginnin and too hot to flavour it in an appropriate way - so I just use it once and leave it in the fridge then for a few weeks - afterwards it ain´t that persistent no more.
And many thx for tellin me what i´ve been experiencin 15 years ago. It´s been exactly that way u described it, even the restaurant itself - fish and chips in a news paper - u seldomly see sumthin like that over here anymore - but it really had style sumhow.
I´ve been lookin up what
Haggis exactly is now.
Yes u are right - it´s the giblets (heart, liver, lungs). They are boiled in a bouillon (u gotta take care that the tracheas is hangin out of the pot, so the "rest of whatever" can drip out and not into the pot). The turned around stomach itself is goin to be washed with cold water, gettin cleaned of the solid remains of the stomach acid and the stomach lining. When the heart/liver/lung is cooked it get´s chopped, saltened and peppered, u put some nutmeg, mace and chopped onions, as well as kidney fat and oatmeal/cornmeal in it and mix it.
Afterwards u fill it into the turned around stomach (don´t fill it up completely otherwise it will go phut), cord the vents, prick it with a fork and put it into boiling water for bout 3 hrs til the stomach itself is cooked. That´s it! But u only eat the filling as far as i read about it. Btw there are several mods of this dish allover the world - in Germany it´s called "Saumagen" ("Sow´s stomach"), almost the same procedure but different meat and spices and potatoes used instead oatmeal.
It is quite poor that the German wikipedia got a manual by a scottish author of cookery books (Paul Harris) and got a paragraph about how tourists are punked by scottish ppl tellin them bout the Haggis animal ...
(There are the Low-flying Haggis which are flyin just above the surface of scottish fields and doin this that fast you can´t even see ´em and ther is the Left-driving Haggis which left leg is shorter than the right to have a better standing on the acclivities of the Scottish Highlands - bad side effect of this anatomic special is that they always get a left-twist

hunting season is only in January - to hunt them u gotta push them into even land since they can´t run away or even stand there caused by their left leg - u can easily attract them with a bagpipe which is imitating the rutting call of a Hagggis)
...and in the english version u don´t even find a kinda recipe. Maybe I should have look it up in the scottish version
