Raw sap is almost flavorless but has a very slight maple flavor. It is not sweet when you taste it. My cousin does maple syrup and maple sugar commercially on his farm and so I have been exposed to sap at every stage of the process. You never process sap in the kitchen because the steam coming off while you cook it down is not just pure water, it can get sticky and you will be in trouble at home if you do it indoors. When I lived closer we would buy an imperial gallon from him every year and never had any left over the next year. He lives just 5 miles north of the Vermont border in southern Quebec. When you get it cheap or free it is amazing how fast it gets used up. His family uses it in place of cane sugar in many things like when making rhubarb pies or sauce. Maple sugar on oatmeal rather than brown sugar is also great. Be careful to not use too much all at one time because maple syrup can act as a mild laxative. I live too far away right now to keep getting syrup at wholesale from him but can see me tapping some of my own trees starting next year.
that's interesting... thanks for posting it up. I bet it is something to see a big pot of sap cooking down... do you use hydrometers to test the viscosity, or just wing it? I may never look a the bottle of my Aunt Jemima ' genuine ' maple syrup in refer the same again... lol. I don't care for thick pancakes or flapjacks... but thin - yes! with butter and syrup... yum. runs close 2nd to my fav... homemade waffles, butter and syrup. my mom used to make them often as kids...
