Use ¾ ripe and ¼ under-ripe fruit to
make fresh juice – commercial/pre-made juice is lower in pectin – and use the
skins/peels where applicable (i.e. apple peels have high pectin content). Wash
fruit, dice firm fruit and crush soft fruit and simmer with water to extract
juice. Strain slowly.
Combine juice and sugar (plus lemon
juice for low acid fruits), boiling hard until set. Remove from heat and
discard foam. Fill hot jars with hot jelly then process for 10 minutes in a
boiling water canner.
