It was impossible for me not to fall in love with every one of the Fields of Mistria marriage candidates, so much so that I've struggled just to choose who I want to date. So I'm just covering all my bases and building up my relationships with all of them just in case.
Just like Stardew Valley, you can get the deep dive details on the Fields of Mistria wiki, which I recommend. Right here I'll be providing the tailored study guide version of Mistria's marriage candidates. I'll tell you which easy gifts to give each character all year round and what you should have your eye on gifting them for their birthdays as well.
Fields of Mistria marriage candidates
Down below I'll run through all the marriage candidates and what you should gift them. This is a condensed version to help you build relationships as easily as possible, but you can find a full list of loved and liked gifts on the player-maintained Fields of Mistria wiki. Here's what I'll be recommending:
Loved gifts: Full list of each character's loved gifts, for reference
Easiest gifts: Gifts that are easiest or cheapest to acquire so you can build friendship year round, most often these are "liked" tier gifts
Birthday gifts: A loved gift (if possible) that's easiest or cheapest to attain in time for a character's birthday, especially if you're still in year 1.
Adeline
Loved gifts: Coffee, gazpacho, lemon pie, middlemist, peaches and cream, plum blossom, pumpkin pie, tea with lemon
Easiest gifts: Tulip (plant in spring), heather (forage in fall), Snapdragon (forage in winter)
Best birthday gift: Coffee
The easiest birthday present for Adeline is coffee, which you can buy from Darcy at the saturday market for just 100 tesserae. It's easier to just grab a hot cup of coffee the Saturday before her birthday and hang onto it. If Darcy isn't selling it that day, go for tea with lemon or pumpkin pie instead. Peaches and cream is an easy recipe (peaches, sugar, milk) which you'll gain after selling at least one peach in summer and may have ingredients on hand for.
Balor
Loved gifts: Alda gem bracelet, chili coconut curry, deluxe curry, family crest pendant, perfect emerald, perfect ruby, perfect sapphire
Easiest gifts: Snowdrop anemone (forage in spring), ruby
Best birthday gift: Perfect ruby
The easiest birthday present for Balor is a ruby. You can find these in the upper levels (1-20) of the mines by mining ruby nodes. The perfect ones are more rare, of course, but I found and sold several of these within my first season, so you should have at least one tucked away by Summer without trouble. If you're really in a pinch though, just give him a regular ruby for his birthday and tell him you were pressed for time.
Celine
Loved gifts: Crystal rose, frost lily, hydrangea, middlemist, plum blossom, rose, snowdrop anemone, spring galette
Easiest gifts: Snowdrop anemone (forage in spring), hydrangea (forage in summer)
Best birthday gift: Hydrangea (forage in summer)
The easiest birthday gift for Celine is a hydrangea flower. Thank goodness this girl is so easy to please. Hydrangeas are one of her loved gifts and they can be foraged in the same season as her birthday. Even if you forget about her birthday until the day of, you should have no trouble running out to the forest east of town and snagging one off a bush.
Eiland
Loved gifts: Chocolate cake, coconut cream pie, glowberry cookies, golden cheesecake, golden cookies, ice cream sundae, mont blanc, pumpkin pie, strawberry shortcake
Easiest gifts: Chocolate, caramel candy, berries and cream
Best birthday gift: Chocolate cake
The easiest birthday gift for Eiland is chocolate cake. Eiland loves food, specifically expensive or hard to make sweets, so his loved gifts are a pain to make until you've invested in your kitchen. You should be able to save up for a tier two kitchen (from the carpenter) and buy a chocolate cake recipe (from Darcy at the Saturday Market) before his birthday. As long as you've got an egg, you just need to pick up chocolate, sugar, and flour from the general store. Failing that, caramel candy is a default recipe that's very easy to make in a pinch with just sugar and butter from the general store.
Hayden
Loved gifts: Golden butter, golden cheese, golden milk, golden duck egg, golden duck mayonnaise, golden egg, golden mayonnaise, pumpkin pie, stone horse, vegetable quiche
Easiest gifts: Egg, milk, butter, cheese
Best birthday gift: Golden egg, golden milk
The easiest birthday gift for Hayden is a golden egg. I'm shocked that Hayden has more premium taste than Eiland but here we are. He's very easy to give regular dairy product gifts to year round but his loved gifts are all golden varieties. His birthday isn't until winter, so if you've got at least one chicken or cow and have been dilligently petting them daily to improve their hearts, you should be producing golden eggs or golden milk by then. If not though, he'll still appreciate the normal milk and eggs.
Juniper
Juniper romance walkthrough
Loved gifts: Ancient royal scepter, black tablet, crystal rose, golden cookies, moon fruit cake, mushroom brew, pizza
Easiest gifts: Middlemist (forage in spring), fog orchid (forage in fall), poinsettia (forage in winter)
Best birthday gift: Mushroom brew, Crystal rose
The easiest birthday gift for Juniper is wine. It's the quickest thing to get your hands on any day of the week at the inn. The rest of her liked and loved gifts rely on luck and foraging. If you ever spot a mushroom brew tea at Darcy's stall or Balor's cart, snag it and tuck it away for Juniper's birthday.
March
March romance walkthrough
Loved gifts: Meteorite, perfect copper ore, perfect iron ore, perfect silver ore, sushi platter
Easiest gifts: Copper ore, iron ore, silver ore
Best birthday gift: Perfect copper ore
The easiest birthday gift for March is perfect copper ore. You might be slightly hard-pressed to find one by his birthday in the second week of spring in your first year, but since you can find them in the upper mines levels (1-20), it's more achievable than his other loved gifts. Barring that, you can give him a regular copper ore instead. He probably doesn't like you that much yet anyway so anything is an improvement!
Reina
Loved gifts: Breaded catfish, cabbage slaw, ice cream sundae, rosemary garlic noodles, seafood boil, seafood snow pea noodles, sushi platter
Easiest gifts: Daffodil, garlic, cheese
Best birthday gift: Cabbage slaw
The easiest birthday gift for Reina is cabbage slaw. Like Eiland, Reina mostly loves food. Luckily, the cabbage slaw recipe is easy to earn and cheap to make as long as you've saved some spring ingredients. You'll get the recipe after you ship just one cabbage in the spring, and cooking it requires one cabbage and one fennel, which is foraged in spring. If you didn't plan that far ahead you can forage some garlic in fall, which is on her liked gifts list.
Ryis
Loved gifts: Golden bristle, golden bull horn, golden cheesecake, golden cookies, golden duck feather, golden horse hair, golden feather, hard wood, lobster roll
Easiest gifts: Stone, wood, lilac
Best birthday gift: Hard wood
The easiest birthday gift for Ryis is hard wood—and I don't want to hear you making jokes about it! Ryis has a very early birthday, so getting him the best gift is tricky, not least because everything else on his loved gifts list is unattainable until much later. In year 1, you probably won't even have a copper axe to harvest hard wood yet (but well done if you do). In year 1, you may have to settle for giving him a regular piece of wood or stone. If you're feeling romantic, you could forage a lilac for him, which he also likes.
Valen
Loved gifts: Beet salad, beet soup, beet, deep sea soup, rosemary garlic noodles, summer salad, sushi platter, vegetable soup
Easiest gifts: Dandelion, garlic
Best birthday gift: Vegetable soup or beet
The easiest birthday gift for Valen is a beet. She really likes beets. The trouble is, beets grow in winter and Valen's birthday is on Fall 1, so this won't work in your first year unless you happen to have bought one from Balor's cart. A year 1 alternative is the vegetable soup, which you can get the recipe for from attending Josephine's cooking class on the request board in spring. You'll need a potato grown in spring and a tomato and basil from summer, which is all attainable in time for her birthday so long as you've reached at least cooking level 16. If you aren't quite that prepared, you can forage some garlic for her on the first day of fall.
