Here's one easy rule that will help you remember the difference between past participle adjectives (bored, relaxed, satisfied) and present participle adjectives (encouraging, falling, irritating):
PAST PARTICIPLE ADJECTIVES are common when you talk about the way you prepare food:
fried fish, a chopped liver sandwich, roasted chicken, baked apples, sautéed mushrooms, Cajun-style blackened trout, stuffed eggplant, poached eggs, percolated coffee, well-steeped tea.
PRESENT PARTICIPLE ADJECTIVES are common when talk about functions or qualities:
working-class children, baking dish, hiking boots, biting sarcasm, sleeping bags, swimming suits.
These are shorter ways of providing defining relative clauses:
trout that has been blackened using a Cajun style
apples that have been baked
a sandwich made of liver that has been chopped
boots that are used for hiking
bags which are meant for sleeping
dishes which are used for baking food.
