Fear of Frying?
Or Tips and Tricks for making a good "Fritto all'Italiana"
Making what the Italian call a light, healthy and easy to digest "fritto" - interpret all that as not the least bit greasy - is a fairly skilled affair, but read through these points and you'll be well prepared.
Which oil?
The important thing is that the oil has a high "smoke point". Once oil starts to smoke it becomes unstable and potentially toxic, so smoking oil is to be avoided at all costs. Olive oil has a high smoke point but, expense apart, it can be too strongly flavoured for many dishes. In Italy peanut (groundnut) oil is usually recommended but grape seed and canola oil are good too, as the little table of smoke points below shows:
Grape Seed 204 °C (399 °F)
Peanut oil 231 °C (448 °F)
Canola 242 °C (468 °F)
How much oil?
Lots! It needs to be deep if you are deep frying, which is what we're talking about here, about 8 -10 cm (3 to 4 inches) and more does not do any harm. This means you need to use a deep pan. Never re-use frying oil, use fresh oil every time.
What temperature?
(If you have an electric fryer where you can set the temperature and leave it the device to regulate it and keep it steady, skip this part)
I never use a thermometer but go by experience, observing how many and what size bubbles have formed. As a general rule, smaller and quicker cooking items like shrimp or fish need a higher temperature 180 - 190 °C (355 - 375 °F) while thicker and "wetter" items like vegetables, where you need to cook off the moisture, need a lower temperature 140 - 160 °C (285 - 320 °F), as otherwise the outside gets too dark while the middle is still uncooked.
The really crucial thing is to maintain a steady temperature at all times.
How do I know when the oil is hot enough without a thermometer?
I use a piece of bread. I throw it when the oil is still coolish. It sinks first and when it floats to the top and begins to sizzle gently with small bubbles forming round it, the oil is ready. Even so it is best to just test with one piece: if your test piece floats and sizzles at once, you can go with the rest, otherwise wait a half minute and try again. If you start frying too soon when the oil is not yet hot enough your first batch will be soggy. Just leave the bread in there, it has a useful role to play in keeping the temperature steady
How do I maintain a steady temperature?
Now we are at the heart of the matter, this is a key section. Bear the following in mind.
- First rule is not to fry too many pieces at once, never overcrowd the pan. The more pieces you put in the oil the more the temperature drops - conversely when you take things out the temperature rises. If the temperature drops the pieces will stick to each other and worse, they absorb more oil and get greasy.
- Be prepared to regulate the heat down or up until you find the right point.
- If the oil seems too cool and you can't regulate the heat quickly enough as when cooking on an electric ring, take out some pieces to raise the temperature.
- It is counter intuitive but if you learn to put some of the next batch in BEFORE you take out the pieces that are done, you lower the temperature for a moment, so that when you empty the pan of the cooked pieces there is less risk of the temperature rising too much. It also means that the oil is never left without some pieces "to work on", the pan never contains just hot oil.
- If the oil has something "to work on" it is less likely to overheat. Leaving that bit of bread in and if necessary putting in another piece or two helps to keep the oil "happy" and to stop it overheating.
- If the oil seems to be getting too hot, cool it down either by putting in bread (or lemon zest or an onion ring, a piece of potato, whatever you have to hand) or by adding a tablespoon of cool oil.
How do I prepare food for frying?
This varies a great deal according to what you are frying. The basic principle is that the items must be evenly sized and that smaller pieces cook better. Except for potatoes, they must be protected from the oil by a coating of flour, considered best for small quick cooking fish and seafood or grated vegetable fritters, or batter (usual for thicker vegetables).
Some vegetable items like fennel, artichoke and cauliflower are best previously blanched and dried. Items that risk melting into the hot oil like ricotta, Mozzarella, potato croquettes and Arancini, the Sicilian rice balls, need an extra layer of protection: egg + flour + batter, or egg + flour + egg + breadcrumbs.
What's the best flour?
Whatever flour you use it needs to be milled very fine, fine as talcum powder, so it coats perfectly and snuggles into every nook and crevice. I use Italian "00" flour or else chickpea flour. I sometimes substitute one third of the regular flour with corn or wheat starch, or rice or potato flour as these all have a very fine texture that helps to seal the food perfectly.
If you are using breadcrumbs, the finer they are ground the crisper, and better sealed, your Fritto will be.
What's the best batter?
For a light batter I omit egg altogether or else I use egg whites only, whisked fairly stiff. Bubbles are a good thing in batter and using cold sparkling mineral water or beer is another trick for making a non-stodgy batter. You add these last minute to maintain maximum bubbles.
An ice cube in the batter is also a good idea - use less liquid to allow for the fact that the ice cube will give some water off as it melts. In general the colder your batter the better.
Some people add a pinch of baking powder or use self raising flour though I never do.
When do I season with salt ?
Never salt the batter or the food and never salt the Fritto until the very end. All fried food needs to have a rest of at least a minute before you salt it, otherwise you risk softening the crisp exterior and wrecking all your good work.
For sweet fritters the same rule applies, do not sprinkle with sugar until after the fried food has rested.
Anything else before I start?
Use a wide draining spoon to allow as much oil as possible to drain off when scooping out the fried food. Rest all freshly fried items on absorbent kitchen paper as soon as they are out of the pan and prepare this paper bed before you start to fry. If you like you can place the fried foods to drain on a wire mesh elevated above the paper but I tend to prefer placing directly on paper.
Fried food is best eaten hot as soon as it is made. There is an Italian saying that the person who fries does not eat - chi frigge, non mangia .You just cook and serve up. But if you want to sit down and eat with everybody else then give everything a brief second fry just before serving. Line your saving platter with paper towels and if you've done everything right there should be hardly any oil on this new batch of kitchen paper-
I don't advise keeping fried food warm in a low oven, it tends to get soggy. I'd rather fry in two batches with a conversation pause in between if there are a lot of diners or a lot of food to fry.
And one last important thing,
This is probably my best tip that I'm sharing here with you. Since it is the thermal shock - the contrast between cold batter and hot oil - that produces a fast and crisp seal, I hold an ice cube in my hand and shake a few drops of the water into the the pan with the hot oil when I put in a new batch. Try it, it really makes a difference.
