Pans made out of aluminum would likely present the same problems. During boiling they might warp out of level, causing high spots that could lead to scorching. If you ran your sap deep that might not be as big an issue though.
What do you boil sap in?
Boiling the sap:
Fill a flat pan or large pot (a “lobster” pot is used in this example) ¾ full with sap. Place the pot onto the heat source. Once the sap starts to boil down to ¼ – ½ the depth of the pot, add more sap, but try to maintain the boil.
Can you boil sap to fast?
Raw sap cannot be boiled too hard. It’s science. Evaporation is a cooling process. The hotter you attempt to get the sap, the faster it evaporates, thus cooling it down.
How long does it take to boil down 10 gallons of sap?
Boiling 10 gallons of sap down to 1/2 gallon took 3 hours (using 3 pans). We brought the almost-syrup into the house and spent another 20 minutes finishing it on the stove. And then we licked every spoon, bowl and pan that had any speck of maple syrup on it.
Do you have to boil sap in stainless steel?
Boiling sap may need to be transferred to a smaller boiling vessel/pan in order to keep the pan covered completely in sap and to prevent scorching or burning the pan. Do this when sap level gets below 1 inch in depth. A smaller stainless stock pot is a good option.
Can you boil cloudy sap?
Treat sap like you would treat milk.
Or just take a gallon of the cloudy sap, put it in 4 pots on the kitchen stove and boil like crazy. Combine the pots into one pot just before they run dry and keep boiling. You can produce a couple ounces of syrup real quick (less than 1 hour) to taste-test some.
When should I stop collecting sap?
When to stop collecting sap
When the temperature remains above freezing or buds start to form on the tree, it is time to stop collecting sap. The sap can have an unpleasant odor and have an off flavored taste, and may also have a stringy appearance.
Is cloudy maple sap OK to boil?
But sap will spoil (it gets cloudy and off-tasting) if it is left too long in storage. So use your judgment as to when you should start boiling based on these facts. It is possible to boil down sap into partial batches of syrup. These semi-finished batches usually will store better than raw sap.
Can you stop boiling sap for the night?
Unless its going to be real cold at night there is no need to remove what you been boiling as the sugar content will keep pan from freezing.
Is it OK for maple sap to freeze?
Sure. And if you are small scale and most concerned with having enough time to boil you can use freeze concentration to increase the sugar percentage in your sap. If you let the 5 gallon block melt, discard block after 1/3 has melted. You can refreeze the melted portion.
What happens if you boil spoiled maple sap?
When the sap reaches 66.9% sugar, it is then maple syrup. Maple syrup that is boiled too long will crystallize and maple syrup that isn’t boiled long enough will spoil quickly and will be watery because the concentration of sugar in the syrup will be too low.
Can you stop boiling maple sap and start again?
Can you stop in the middle of boiling maple sap, then start up again? Yes, since it typically requires long periods of time to boil down sap, it is quite common to boil the sap for several hours one day, then cover the sap or put it into a refrigerated environment overnight, and then continue boiling the next day.
At what temperature does sap become syrup?
Sap becomes syrup (66-67% sugar content) at approximately 7¼oF above the boiling point of water (ex. if water boils at 212oF, proper density for syrup would be slightly over 219oF). Concentrations below 66% sugar content can sour over time.
What temperature does sap boil at?
The sap should be at a boiling temperature around 217°F to 218°F. Transfer the concentrated sap to a smaller boiling pan or pot and complete the finishing process on a controlled heat source such as a gas burner, camp stove or kitchen range.
