Wash and chop the rhubarb into small, even pieces. Ensure the pineapple is undrained but well mixed if separation has occurred in the can.
In a large, heavy-bottomed pot, combine the chopped rhubarb, undrained crushed pineapple, sugar, and lemon juice.
Stir the mixture over medium heat until the sugar has fully dissolved and everything is well combined, about 5 minutes.
Raise the heat to medium-high and bring the mixture to a rolling boil, stirring constantly to prevent sticking or burning.
Reduce the heat to maintain a steady simmer. Continue cooking for 30-35 minutes, stirring occasionally, until the mixture thickens and reaches the desired jammy consistency.
To test the doneness, place a small amount of jam on a chilled plate and let it sit for a minute. If it holds its shape and wrinkles when pushed with your finger, it's ready.
Remove the pot from the heat and let the jam rest for 5 minutes, stirring occasionally to distribute the fruit evenly.
Ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace at the top. Seal the jars with clean lids and rings.
Process the jars in a boiling water bath for 10 minutes if planning to store long-term, or simply let them cool and refrigerate for immediate use.
Store unopened jars in a cool, dark place for up to 1 year. Once opened, refrigerate and consume within 3 weeks.
