Extracts are super simple and don't need more than a paragraph to explain. Mainly it is a side item I do with leftover or food waste.
Place peels, seeds or leaves (tear the leaves) in to jar. If you don't have enough to stuff the jar full, it can be added to over time. Pour vodka, moonshine or rum over them. The stronger the alcohol the better. Tightly screw on the lid, then set out of your way and out of your mind for a week, vigorously shake. Do this for four weeks. Strain and place into a separate jar. Do not open near a flame.
You will need oranges, peeled and segmented
Water or orange juice or a light syrup of your making ( basically a sugar water mix, the more sugar the heavier the syrup). I prefer a lite sugar water to a syrup as it helps the oranges taste fresher.
Place your orange segments in your sterile jars, leaving an inch of head space, as they tend to float. Bring your liquid to a boil, then pour over the tops, leaving a half inch of space. Lids on tightly, and water bath.
Lower altitudes, 5 mins. Middle of the road 10 minutes. Higher altitudes, 15 mins.
This is usually finished before you are done candying the orange peels.
