place petals in a large non reactive mixing bowl
boil water and pour two full cups over the petals
cover and let the petals steep for at least two hours, I let mine steep 6 hours
drain through cheesecloth or a couple of coffee filters in a strainer
while the juice is draining set up your canning pot for a boiling water bath (directions there!), wash jars and fill with hot water and wash lid and rings well and keep hot in a small pan
you should have close to two cups of juice, add a water to get to two cups if needed
pour into a medium size heavy bottom pot
add the lemon juice and calcium water
bring to a boil stirring occasionally
mix the sugar and powdered pectin together
when the juice is boiling and can't be stirred down add the sugar/pectin mixture
stir to make sure the pectin gets completely dissolved
cook and stir for 30 seconds
remove from heat, skim any foam and pour into hot jars
wipe the rim, place a hot lid and a clean ring on the jar and carefully hand tighten(the jar is hot be careful)
process for 5 minutes in a boilingwater bath or put in the fridge for immediate use
