| FAULTS |
COMMENT
AND ACTION |
| (a)
Pastry hard and tough |
Too
much protein has been extracted from the flour due to incorrect
levels of ingredients and/or too much working.
1. Reduce the water and increase the fat.
2. Check mixing, rolling and handling.
Note that excessive rolling and handling contribute to working
of the pastry. |
| (b)
Pastry soft and crumbly |
Insufficient
protein has been extracted from the flour due to incorrect
levels of ingredients and/or too little working.
1. Reduce fat and increase the water.
2. Check that mixing is correct.
3. The presence of too much baking powder may cause the
effect
described. |
| (c)
Pastry blisters |
This
may be due to insufficient mixing of the fat and flour,
or the addition of too much water.
1. Ensure that a crumbly biscuit-like texture is achieved
when
mixing fat and flour.
2. Reduce the amount of water so that excess does not
eventually escape as steam on baking causing blisters. |
| (d)
Pastry shrinks |
Shrinkage
is generally due to over stretching the pastry. This happens
with over rolling or incorrect rolling. Remember that pastry
is effectively pressed down to its required
thickness. Shrinkage will also occur if the pastry has not
been allowed to rest for several hours overnight. See Soygold. |
| (e)
Speckling |
This
is due to deposits of flour on the pastry surface and should
be brushed off before baking. |
| (f)
Difficulty in moulding with pastry collapsing (hot pastry) |
1.
Allow pastry sufficient recovery time, ideally overnight
so that it
may harden and cool.
2. Check that there is not too much water in the pastry
recipe.
3. Ensure that boiling water is added to the pastry so that
the
starches are solubilized and set. See Soygold. |
| (g)
Pastry cracks (hot pastry) |
This
may occur due to a variety of errors.
1. Increase the water if there is insufficient present.
This will extract
more gluten.
2. Make sure the dough is sufficiently mixed so that the
paste is
strong enough.
3. Make sure that flour is not trapped in the dough during
blocking
or rolling.
4. Make sure that boiling water is added to the dough during
mixing. |
| (h)
Pastry hard and brittle (hot pastry) |
This
is due to the pastry being too dry and may be improved by
adding more fat and/or water. |
| (i)
Puff pastry lacks flakiness |
This
may be due to: -
1. Margarine too warm, use cool margarine from the refrigerator
otherwise it will mix too well with the flour.
2. Insufficient resting and chilling. The pastry should
rest for several
hours or overnight in a cool place.
3. Too heavy rolling. The layers of pastry created by folding
and
rolling are squashed together and give little flakiness
on baking.
Rolling to the desired thickness should be done gradually
with
care. |
| (j)
Puff pastry goes short |
With
hot and cold pastry, the fat is rubbed well into the flour
to give shortness in the finished product. However, with
puff pastry the fat should not be rubbed in so well.
1. Make sure the temperature of the dough and margarine
is cool.
If the fat is too warm and soft it will mix too well with
the flour.
2. Dont roll the pastry too heavily as this will also
mix the margarine
and dough |
