Hints and recipes for production of “gnocchi” (potato dumplings)
Gnocchi are made with a dough consisting mainly of fine ground flour
(“00”) and potatoes or by-products such as potato four, potato flakes,
ready-mixes, etc.,as we shall see further on.
Other ingredients used in the mixture are: water, eggs (on average 1 egg
per Kg. of product), salt, seasoning, vegetables such as pumpkin, nettles,
spinach or other to obtain coloured and flavoured gnocchi. When
vegetables are used, these have to be well squeezed to eliminate excess
water, if necessary the moisture can be corrected by adding a little flour.
Some recipes follow for gnocchi made with potatoes, potato flakes and
ready mixtures respectively.
However, each recipe can be changed according to taste and/or the
experience of the user.
Potato dumplings:
Boil the potatoes with peel the day before, drain them and peel them while hot,
leave them to cool and dry (if this is not possible, place them in a hot oven for 20
minutes).
Sieve them or use a mincer, incorporate 300/400 gr of flour for each Kg of
potatoes, an egg, salt, other seasonings (for example nutmeg) and mix well for
2-3 minutes.

Machine description IMPERIA & MONFERRINA S.p.A.

If the mixture is too wet, add a minimum dose of potato flakes or ready-mix for
potato dumplings.
Potatoes Kg 2 – potato flakes Kg. 0.5 – flour Kg 0.5
Potatoes Kg 2 – flour Kg 0.4 – ready-mix for potato dumplings Kg 0.4
Potatoes Kg 2 – ready-mix for potato dumplings Kg 0.6
Gnocchi with potato flakes:
Ingredients: 2.5 Kg flour, 1.5 Kg potato flakes, 100 gr salt, 5 litres water -
separate: 2.5 litres water, 1 Kg potato flakes, 10 eggs.
Procedure: bring the salted water to the boil, add 2.5 Kg of flour and 1.5 Kg of
potato flakes and mix for a maximum of 3 minutes while cooling.
Add 1.5 Kg of potato flakes already mixed with 2.5 litres of cold water and 10
eggs. Mix to obtain a smooth paste.
Gnocchi with commercially prepared ready-mix:
Mix the doses of product and water indicated in the instructions taking care to
use hot water at 80 – 90°C.
Some products may be mixed with cold water; see manufacturer’s instructions.
Always remember that the flour unit has to be fed with sieved rice flour or fine
ground flour. Other types of flour are not suitable.
Description of the machine
The Monferrina G2 was designed to produce gnocchi using a piston type
feed system. The device presses and extrudes the dough without
affecting the texture and is therefore perfect for producing extremely soft
gnocchi.

If, to be able to carry out a specific specialised technical operation on an
electrical electronic device of the machine, it is necessary to work with the
electric cabinets or control panels open and in exceptional cases with the
main switch in ON position, be very careful and work with extreme
caution. During these operations high voltages inside the electrical-
electronic devices are a hazard for the life of the personnel.
Before restarting the process always pay maximum attention and make
sure there are no operators still inside the machine operating area
indicated by the danger signs.
Parts subject to wear due to the work they perform are to be checked
and replaced as soon as they show significant signs of wear.
The manufacturer has designed and built the machine for a logical
life, taking into account the normal use conditions of the Customer;
however, it is necessary to periodically check all these components
very carefully.
If “mechanical cracks” and/or permanent or cyclic structural
deformations are found, contact the manufacturer or skilled
technicians immediately, who will take the necessary action.

Safety devices
Caution!
The components indicated are particularly important for safety.
In the case of failure or wear, they are to be replaced with spare
parts supplied or authorised by the manufacturer.
During machine use all the protections are to be correctly mounted.
Thermal relays
Located inside the electrical box there are devices that prevent the motors
from overheating.
When one of these devices trip out, it must be reset as follows:
•Turn the main switch to the “0” position.
•Open the electrical box; each relay has a button that jumps
outwards when the device is activated.
To reset the device, press the reset button located next to it. If the reset
button does not remain inserted, wait a few minutes for the device to cool
down and then press the reset button again.
Fuses
Located inside the electrical box for protection of the machine’s auxiliary
circuit; any power surge could cause the fuses to burn out. When a fuse
has burned out, proceed as follows:
•Turn the main switch to the “0” position.
•Open the electrical box; with the aid of a tester, identify the burned
out fuse and then replace it with another of the same amperage.
Caution!
Repeated burning out of the fuses could be caused by problems
within the electrical unit; in this case contact the Technical Service
Department.
