The OP was looking for rhubarb in February,
I have frozen rhubarb and it works great.
. Even those who can afford it will not pay four times the normal price for a cauliflower - and rightly so!
Well at my age my philosophy is good food is not cheap and cheap food is not good.
If it is healthy for you I buy it.
I eat No grains (bread), pasta's, white rice, potato's, ground meats nor do I drink soda pop or sugary drinks.
This justifies me the extra money to buy the more expensive foods that keep me lean at fighting weight.
Fresh berries, nuts and greens are a must no matter the price tag in my book.
Most can be bought during season and put in the freezer.
I'm sure people in Poland have freezers don't they.
