The Science of a Yorkshire Pudding
Many many people ask me about “yorkies”, as a lad I
always had them bathed in thick gravy before my Sunday dinner.
As well having a couple with the dinner, my starter was baked in
a loaf tin. Now I use them either in a loaf tin or a flan tin, and fill
them with a thick lamb stew or hot pot.
But so many people have problems with them, even with packet
mixes too.
What about these problems many people have making
them . . . why do they not rise? Why do they fall flat? Should they be
crisp or soft? The latter for me is a totally personal issue, some like
them soft, some crisp on the outside and soft in the middle. When you
lash them with a gravy does it make any real difference?
But to answer the main problems people have with
them, rising and falling flat. One must think and understand about why
and how this happens to answer it. They rise mainly because of the egg
content in the mixture . . . NEVER add baking powder! For this rising to
occur the mixture needs instant heat, this creates steam and they puff
up and rise - so the oven, etc must all be pre-heated, a slow gentle
heat or cold oven will not work.
They will fall flat if they are removed from the
oven too soon. If they do not slightly crispen on the outside the
structure of the egg and flour mixture does not fully 'dextrinise'
meaning its structure will not hold its own weight . . . think of
building a sky scraper out of wood, eventually it will buckle and
collapse under its own weight.
Cooking times will always vary, as everyone's oven
is slightly different and because we tend to open and close the door to
remove the meat, the potatoes, etc. So the 12 minutes I have given here
is approximate only, one will need to judge and modify accordingly.
Yorkshire Pudding: The secrets
* To get a good rise one must fill the mix with as
much egg as possible using only a drizzle of milk. Unfortunately the
recipe here then is not 'foolproof' in amounts, as I cannot guarantee
the size of eggs that you use and they do differ in amount by as much as
20gm per egg, so it is best to adjust the flour rather than the egg. The
trick is to pack the mixture with eggs!
* Use deep sided muffin trays and heat these trays
up prior to use
* Put in a good measure of hot oil into each mould.
If the oil is really hot, until it just starts to give of a slight haze
but not quite smoking (approximately 180°C) the moment the batter is
poured in, it will sizzle, begin to cook and rise at the sides
immediately. This gives that 'hollowed' centre look that can be filled
and will hold the gravy
* Do not worry about the oil content too much: if
you want perfect 'Yorkies' you have to live with it and most of it will
still be there when they are cooked and can be poured away for re-use
when you remove the final, cooked product
* With experience one will be able to judge when
they can be removed and not fall flat / deflate. If you notice that they
are beginning to, pop them straight back in for a few more minutes, this
allows the correct amount of hardening / crispening of the outer walls
to develop and holds the shape and size
