Haverkoekjes

2026-04-07T19:27:01Z

Joosteto:

* 370 g water
* 550-650 g rijpe bananen (~7 bananen, met rijpe peren werkt ook)
* 900 g havervlokken
* 550 g mix van noten, rozijnen, cranberries (180 g noten+cranberry mix + 370 g rozijnen)
* 40 g kaneelpoeder
* 20 g gemberpoeder
* 50 g zonnebloemolie

Eventueel:
* 1 mg B12 (oplossen in water)
* 40 g Calciumcarbonaat
* 40 g chiazaad (samen met water weken)

Prak de bananen, meng alle ingrediënten in een kom totdat er een egaal deeg ontstaat. Laat het vocht daarna nog een half uurtje in de haver trekken, zodat het deeg niet meer plakt.

Maak bolletjes van +/-40 g, en leg die op regelmatige afstanden op bakpapier (op rooster of eventueel bakplaat). De koekjes gaan niet uitlopen, dus ze mogen dicht naast elkaar liggen.

Bak +/- 40 min op 170 graden

Joosteto:

* 350 g water
* 550-650 g rijpe bananen (~7 bananen, met rijpe peren werkt ook)
* 900 g havervlokken
* 550 g mix van noten, rozijnen, cranberries (180 g noten+cranberry mix + 370 g rozijnen)
* 40 g kaneelpoeder
* 20 g gemberpoeder
* 50 g zonnebloemolie

Eventueel:
* 1 mg B12 (oplossen in water)
* 40 g Calciumcarbonaat
* 40 g chiazaad (samen met water weken)

Prak de bananen, meng alle ingrediënten in een kom totdat er een egaal deeg ontstaat. Laat het vocht daarna nog een half uurtje in de haver trekken, zodat het deeg niet meer plakt.

Maak bolletjes van +/-40 g, en leg die op regelmatige afstanden op bakpapier (op rooster of eventueel bakplaat). De koekjes gaan niet uitlopen, dus ze mogen dicht naast elkaar liggen.

Numpy surprises

New in numpy version 2: numpy int types aren't promoted to bigger types in operations that involve a python int:
>>> np.__version__
'2.2.4'
#
np.uint8(1) + 255
<python-input-21>:1: RuntimeWarning: overflow encountered in scalar add
np.uint8(0)
#
# When the value of the int is bigger than would fit in the numpy type, an error is thrown:
np.uint8(0)+256
Traceback (most recent call last):
File "<python-input-29>", line 1, in <module>
np.uint8(0)+256
17:13, 11 December 2025 (CET)17:13, 11 December 2025 (CET)~^[[User:Joosteto|Joosteto]] ([[User talk:Joosteto|talk]])
OverflowError: Python integer 256 out of bounds for uint8

The old numpy 1.24 used to promote numpy int types to 64-bit:

np.__version__
'1.24.2'
#
type(np.uint8(1) + 1)
<class 'numpy.int64'>
#or to bigger types, if needed
type(np.uint8(1)+2**63)
<class 'numpy.ulonglong'>

Also funny: the old 1.24 numpy 'promoted' the uint64 type to float when confronted with python int:

np.uint64(1)+1
2.0
type(np.uint64(1)+1)
<class 'numpy.float64'>
#
#But... uin32 isn't promoted to float, but to... int64(!)
type(np.uint32(1)+1)
<class 'numpy.int64'>
#
# Same as uint8:
type(np.uint8(1)+1)
<class 'numpy.int64'>
#
# However, the signed versions, numpy.int64, numpy.int32 are just always converted to numpy.int64:
type(np.int32(1)+1)
<class 'numpy.int64'>
#
np.__version__
'1.24.2'

This is all improved a lot in numpy 2:

type(np.uint64(1)+1)
<class 'numpy.uint64'>
#
type(np.uint32(1)+1)
<class 'numpy.uint32'>
#
type(np.int32(1)+1)
<class 'numpy.int32'>
#
np.__version__
'2.2.4'

And without warning/exception:

2**np.int8(8)
np.int8(0)
#
np.int8(2)**8
np.int8(0)
#
np.__version__
'2.2.4'

OverflowError: Python integer 256 out of bounds for uint8

The old numpy 1.24 used to promote numpy int types to 64-bit:

np.__version__
'1.24.2'
#
type(np.uint8(1) + 1)
<class 'numpy.int64'>
#or to bigger types, if needed
type(np.uint8(1)+2**63)
<class 'numpy.ulonglong'>

Also funny: the old 1.24 numpy 'promoted' the uint64 type to float when confronted with python int:

np.uint64(1)+1
2.0
type(np.uint64(1)+1)
<class 'numpy.float64'>
#
#But... uin32 isn't promoted to float, but to... int64(!)
type(np.uint32(1)+1)
<class 'numpy.int64'>
#
# Same as uint8:
type(np.uint8(1)+1)
<class 'numpy.int64'>
#
# However, the signed versions, numpy.int64, numpy.int32 are just always converted to numpy.int64:
type(np.int32(1)+1)
<class 'numpy.int64'>
#
np.__version__
'1.24.2'

This is all improved a lot in numpy 2:

type(np.uint64(1)+1)
<class 'numpy.uint64'>
#
type(np.uint32(1)+1)
<class 'numpy.uint32'>
#
type(np.int32(1)+1)
<class 'numpy.int32'>
#
np.__version__
'2.2.4'

And rounding:

0.001*2**np.int8(20)
np.float64(0.0)
#
0.001*2**20
1048.576
#
0.001*2**np.int8(2)
np.float64(0.004)
#
np.__version__
'2.2.4'

Joosteto:

* 250 g water
* 550-650 g rijpe bananen (~7 bananen, met rijpe peren werkt ook)
* 900 g havervlokken
* 500 g mix van noten, rozijnen, cranberries (200 g noten+cranberry mix + 300 g rozijnen)
* 35 g speculaaskruiden (bv 25 g speculaas + 10 g gember)
* 100 g zonnebloemolie

Eventueel:
* 1 mg B12 (oplossen in water)
* 40 g Calciumcarbonaat
* 40 g chiazaad (samen met water weken)

Prak de bananen, meng alle ingrediënten in een kom totdat er een egaal deeg ontstaat. Laat het vocht daarna nog een half uurtje in de haver trekken, zodat het deeg niet meer plakt.

Maak bolletjes van +/-40 g, en leg die op regelmatige afstanden op bakpapier (op rooster of eventueel bakplaat). De koekjes gaan niet uitlopen, dus ze mogen dicht naast elkaar liggen.

Bak +/- 40 min op 150 graden

Joosteto:

* 230 g water
* 1 g gist (kan ook minder)
* 300 g meel
* 3 g zout

(of: 220 g water; 320 g meel?)

Eerst het water en gist, dan het meel erbij en goed doorroeren.
Laten rijzen (8 tot 10 uur).
Strooi ruim meel over deegklomp en plek om het deeg te vormen, zodat het deeg niet zo plakt.
In stokbrood-vorm op bakplaat leggen, en 27 min op 170 C bakken.

Haverkoekjes

2025-07-27T14:00:17Z

Joosteto:

* 500-580 g rijpe bananen (5 tot 6 bananen, met rijpe peren werkt ook)
* 800 g havervlokken
* 500 g mix van noten, rozijnen, cranberries (200 g noten+cranberry mix + 300 g rozijnen)
* 30 g koekkruiden (bv 20 g speculaas + 10 g gember)
* 150 g zonnebloemolie
* 180 g water

Eventueel:
* 1 mg B12
* 40 g Calciumcitraat

Prak de bananen, meng alle ingrediënten in een kom totdat er een egaal deeg ontstaat.

Maak bolletjes van +/-40 g, en leg die op regelmatige afstanden op bakpapier (op rooster of eventueel bakplaat). De koekjes gaan niet uitlopen, dus ze mogen dicht naast elkaar liggen.

Bak +/- 25 min op 150 graden (of 40 min als je bolletjes maakt).
