My friend just returned from Brasil & Argentina.
She brought me a jar of Mermelada de Rosella.
The ever helpful free translator gives back the obvious "Rosella jam".
The picture on the front looks like some kind of flower bud possibly.
What is mermelada de rosella made of ?
Thank you, no, there is no ingredient list on the jar
.
What other jams/jellies/preserves ardo you think are worth searching out on a visit south?

It is made from the dried flowers of Hibiscus sabdariffa. It is known in Mexico as "flor de jamaica" and is served in a sweetened infusion, chilled and iced, as agua de jamaica. It is known as "roselle" on the island of Jamaica, whence it's (generalizing here) South American and Mexican names derive: "rosella/roselle" and "jamaica." It is also the "red" in Red Zinger tea.
Jamaica/Roselle/Rosella is purchased dried, by the ounce/pound or gram/kilo. Toss roughly a large handful into approx a quart/liter of boiling water, simmer 5 minutes, cover, and remove from the heat. Allow to steep. Strain and sweeten to taste.
As for the jam, you will either need to utilize pectin or combine the flowers with a pectin-rich fruit, such as apples ... especially crab apples (which may necessitate additional sweetening).

It has a very tart, spicy flavor, and is rich in vitamins A & C ... aside from being very refreshing.
